Unexpected Changes in Appearance - 1 Month Post Op Double Jaw Surgery

Hi everyone, I am a 19 year old male patient who underwent Orthognathic surgery on 9th of May 2018.
As of now, I am sitting at 1 month post operation, and I don't really like my results.
For a couple of years, I knew I needed to have a double jaw surgery in order to correct my bite, because I was diagnosed with a Class III Malocclusion, underbite. What I always hated about my face was the protruding lower jaw that always made me self-conscious about my side profile and the tilted line of teeth that made me dislike my frontal view.
So the day came, and I had my double jaw surgery. Sadly, the procedure was not exactly like how I expected everything to go. They made an impaction on the right side of my upper jaw to correct the tilted line, and rotated the mandible clockwise to have it in the correct position. But here is the twist: To correct the underbite itsself, instead of moving my lower jaw back, they moved my maxilla forward. This is where I think it all went wrong.
So as I said before, I disliked my protruding lower jaw in the first place, now not only my lower jaw is protruding, my whole jaw is pushed forward making me look like a chimp. Another thing that I didnt really expect, is that by moving the maxilla forward, me nose is now totally flat and looks big especially when I smile. I read many reviews, recovery blogs, saying that in time it will get better but the weeks are going by, and I keep thinking its getting worse and worse. Is it possible that I am still swelling which creates an illusion or is this actually the result? It feels really weird, I lost my former face, making me feel like I lost my identity. I don't look like my sister anymore which was a super strong bond that we had for our whole lives.
If anybody can relate, or has some comment about all this, any advice, I would very much appreciate it as I am feeling a little down right now. I'll attach some pictures to show what I mean.
Thank you all very much!

Hi everyone!

First of all, thank you for all the kind comments!
So I am now 6 weeks post operation, and just came home from the orthodontist appointment. I went ahead and asked whether there was any medical reason as to why it was my maxilla that was moved forward and not the mandible backwards, and voila, there was absolutely no reason. So it could have been a different procedure, one that I would have liked to get (this is why I think I could have made a difference), but alas it's in the past now. Now the orthodontist is regarded as the best the country, him and the surgeon have collaborated to fix extremely complex cases from fractured skulls to serious deformities. So he said that the maxillary advancement was miles better than anything else in my case aesthetically, well I don't think that is exactly how it is, but I do have some trust. Now I am slowly learning to accept my new appearance, but still after 6 weeks post op, I still have the feeling that my whole jaw is protruding a little bit forward, the swelling has settled a little bit more I think, but I am still seeing a chimp more than anything, I guess I'll have to get used to it...
I have a front shot and a side shot attached to the update.

P.S.: Good news though is that my teeth are straight and aligned so well that I will get my braces removed at the end of August, just in time before I start university. I did not expect it to come off that early but I was pretty happy to hear that. I'll definitely post more updates as the time flies by, thank you all who are following my post!

Once again, I thank everyone for the kind comments!
So this is probably gonna be more of an uplifting post than what happened so far.

As I started to return to social life and began hanging out with friends again, I became more and more confident with the new look I got from the surgery. Most of the people didn't even notice a difference, others said it differed a little bit but in a good way, some people even noted that I appeared 'handsome', who didn't find me handsome before. This really boosted my confidence, and helped me to accept the new jaw a lot. That of course was not the only thing that guided me through the rough time.

It was probably said enough times, but the swelling after this procedure really does take a lot of time to settle. Although slowly, the swelling is going down and I have started seeing more of my old self again, and as I am sitting at only 8 weeks post op, there is still a lot of recovery time left, and I believe that it will get even better. At my dentist there is a girl doing work practice, who went through the same surgery just a month before I did. Every time I had a post op appointment, I would spend some time talking with her about the recovery, and man, did it push away my worries. It feels really good to actually talk to someone who fully understands what you are going through.

And of course, I can't thank you guys enough for posting a lot of very helpful comments that made me research a lot on the topic of maxillary development and facial structure (Especially watching Mike Mew). I learned so much about the importance of forward facial growth and how it affects airways, TMJ movement and many many other important functions, as well as aesthetics. I now believe the decision to move my maxilla forward was definitely the right move, and now I know I would not take it back.

Of course, the most important thing, the whole reason I decided to go through the surgery of course, is proper jaw function. It now feels so good as I finally was given the green light to eat again. I can properly bite now as my teeth sit beautifully on top of each other, not having an open gap in between. My back teeth are touching on both the right and the left side now, which makes it so comfortable to chew food, and the resting position of my mouth is so relaxing finally.

I'll attach a couple of photos, finally one where I don't make a pale face, but look like someone who is actually starting to enjoy life :D And a comparison photo where I tried to put the post op pic in the same angle as the pre op pic, and now I clearly see that I had a pretty sunken in midface, which I am glad is now in its correct position.

I am very eager to see the result in two months time when my dentist will be removing my braces and my journey in orthodontics will finally be ending.

I will definitely post more updates, thank you all who are following my post once again!
