FDL tummy tuck in 2019. Pregnancy and weight gain have caused big changes. Where do I go from here? (Photos)

So a little back story, I went from 260lbs to 135lb back in 2018/2019. I did not do proper research for a plastic surgeon and I also didn’t even maintain my weight loss for more than a year before surgery. I got a FDL tummy tuck and did not take care of my scars / healing / follow up at all after surgery. I had no lymphatic massages, I got my drains taken out at a walk in clinic because my surgeon wouldnt remove them, and I found out she is actually certified as a wrist surgeon not a plastic surgeon. I had my surgery Nov 11 2019 and found out i was pregnant in April of 2020. This caused me immense pain, my scaring to get messed up as my belly stretched out, and then I gained a lot of weight postpartum as well. This also put me into a depression for next 3 years. I am now back up to 260 lbs , and have been maintaining that weight since early 2023. I actually dont mins being plus sized. But I hate my body now more than I have even before the weight loss. The way my body looks now has caused me dark thoughts, clothes dont fit me properly, and I don’t know what to do to fix it. Having more knowledge now, I wish I had never gotten my FDL surgery, and it is one of my biggest regrets in life. I miss my old body. I wish I had done proper research.
