Nipples went back in

I am crying making this post because of how devastated I am of my results. I provided a photo of what I started with, my nipples would occasionally fall completely in from wearing a sports bra all day and the left one never came out even with stimulation. My left nipple I had no sensation in it all where I could pinch and pull it at a shocking amount with no pain. My right nipple would come out with stimulation but would occasionally lay flat and rarely completely invert along with the left that mostly stayed inverted. After my procedure I was extremely happy with my results. I felt euphoric, feminine, and overall more confident because I could now consider myself looking like a women under my shirt rather than just flat like it had been my entire life. I also gained sensation in my left nipple, I'm sure it was because I have never felt air/breeze gaze upon it, it was amazing the first week. As the second week came around I noticed just over one night the change in projection, I knew that this would be one of the complications that may arise but was really really hoping it wouldn't be me. I am on my third week of recovery and my nipples have almost completely gone back to being flat. It's so devastating and embarrassing because of the amount of money I saved and spent on this procedure. During my recovery I was very cautious and even took off from work for two weeks. I don't know if it was my fault that they fell flat, or if I was assuming that how they looked directly after surgery would be how they healed. I just don't know what to do at this point because I am not only 2,000 dollars down but feel regret from thinking I could change this. Do I have any other options moving forward? When is the soonest I could get this surgery again? Would injections in my nipples be a good option? Could it have been something I did during my healing process? My doctor didn't provide any covers to help protect my nipples during the healing process, just said to not wear bras or any tight clothing. I noticed that other surgeons apply a thread through the nipple and hold it with a cup that stays for about a week after surgery once I did further research because it felt odd I didn't have any coverage to protect them. Is this an outdated process or was my surgeon right on not advising just wearing loose clothes? Any responses are helpful through this healing process because I have no where to turn for advice besides my surgeon but even then, I can't afford to get it fixed and I feel cheated of my money either way if I did reach out. Thank you.
