Need advice on how to fix chest

Jesus, I lost way more weight and my skin bounced back fine.

me too. I lost about 110, OP lost the genetic lottery I guess.

Keep lifting. Your chest will eventually fill in, if you work hard enough. It's not going to happen overnight though. I'm talking 4 years from now, if you're dedicated. Speaking as an ex obese.

Just out of curiosity, how old are you?
