6 years ago I lost 96lbs. And I looked great in clothes. But I did not feel great because in my mind I saw crinkly skin and not the body I had dreamed of. It was a tough reality check to what I was and what I thought I would look like.
I was in such despair over it I ended up gaining weight back. And I regret that horribly.
Now here I am I don't have as much to lose but I still have weight to lose and I am not older.
I would not go on the drugs. I would do what you know works for you and ignore the drs advice.
I will tell you that working out helps the body bounce back a little. You are young. And while there may be some things you don't like about the way you look, Would you feel better with 70 extra pounds? I don't think so.
It is so tough to face reality, especially when it is not what you thought it would be. I have been there but I know that while I may never look like cindy crawford, I will be strong and healthy.
Don't beat yourself up. You did an amazing thing, Without drugs, I might add.
Hugs because I know how you feel.
