Hey
Even though I'm still new here myself, welcome
I know what you mean. My whole life I've been between a size M and L. Its very upsetting to just see that all go away. For me, the weight is my biggest issue too and it bothers me all the time. Its just nice to know that there are people who I can relate to now and know what it's like going through all of this.
As for having a baby, I'm very worried about it. My family doctor told me that I should be able to have kids, but it'll be difficult and I might need medications to help aid that. I've always wanted to have kids and I'm really hoping that I can get all of this sorted out.
