18 Year Old-Weight Loss of 100 Lbs-no Skin Elasticity

Hi! I'm 18 years old and I recently lost around 100 lbs after being overweight most of my life. As a result, I have a LOT of excess skin covering most of my body-with the worst area being wrapped around my abdomen. I know for sure that I am getting a tummy tuck, but I want to pair another surgery to go along with it. I was thinking of getting a breast lift. The only problem is that if I do get it, when he removes all the excess skin I will go from a solid B cup, to a small A cup. I am considering implants, but I'm worried about the effect it could have on breast feeding (not planning to get pregnant for AT LEAST 8 years) and the other side effects. Any advice would be GREATLY appreciated-especially those who have gotten pregnant after implants! Hopefully I can get my surgery over Christmas Break this year, as I will be attending college as a freshman in the fall.

I have finally gotten my second consult scheduled! Unfortunately, I couldn't get in until August 18, two days before I move into my college dorm. Hopefully, I can choose between the two PS and get my surgery scheduled for sometime around December. I have about a month off for holiday break, so I think that's the best time to do it. Is it reasonable to believe I can get the surgery that soon? I hope so.. I'm so ready for this loose skin to get off my body, and stop influencing my self esteem. After losing all that weight, I still feel depressed because of how my body looks, and it takes a lot to remind myself of all the work I did.
I have decided that I believe I want breast implants. Ultimately, I feel like I should try and keep as much of my skin as possible, and to do that, I need to get implants. Also, my wider torso would not look very proportionate with small A's, so I feel like I would achieve a better look with say, a mid C?
Any feedback is greatly appreciated!
Hopefully, I can upload some pictures later, just a little self conscious!

I have recently looked into full lower body lifts as an alternative to the tummy tuck, and I think it might be for me. Ultimately I will ask the plastic surgeon at my next consult for his professional opinion, but I'm very confused. I believe I will also need a little work on my inner thighs as there is extended visual wrinkling forming "pouches" along the inner side. To be honest, I can live with the little looseness I have on my outer thighs(it's better than the fat I used to have!), and my butt is okayish...I will just wait and see what the PS suggests! I just can't wait to finally see the results of my hard work of dieting and exercising pay off.
