Weight gain

I decided three months ago that I wanted to leave all the bullshit behind…meth,“friends” and a very toxic relationship… I knew I had let myself go too far …it was a “weekend” thing and became daily, then hourly … I still looked healthy,family had no idea,i was very “normal”. I’m very pretty…always been on the thick side and that never changed but in three months I have gained 15lbs!!! but I look so much bigger than 15lbs …i feel gross,I started working out but it’s like soooo hard to lose weight the healthy way ,but fuck yeah I’m going to do it. I just hate my confidence level at the moment.
