Lose skin... does it go away?

I just had my second baby. My first I was so tiny I had no extra skin. This baby was huge so I was as well. Now I have so much loose skin. He’s 4 weeks and I’ve been back to skinny for a few weeks but I still have the extra skin and it’s embarrassing. I’m only 20 so I feel like I ruined my body. I’ll never be able to wear a bikini again. Or crop tops. Or tight fitted clothing. I hate it. Does it go away? Are there any workouts or anything I can do to make it go away? I’m honestly seriously considering a tummy tuck or whatever the surgery would be
