I’m 17 and can’t seem to loose weight?

Hi all, I don’t know if this is the right group to post in but I need some serious help.

I’ve battled with my weight since the age of 8, because before that I was severely underweight , and the doctor told me I needed to gain weight, I just gained too much 😔

It was never really too bad until I started on antidepressants at the age of 14. My weight just kept climbing and climbing and I tried all I could to get it off, but nothing worked.

Fast forward almost 4 years and I’m even heavier, a lot heavier than I should be.

I hardly eat anymore, I’m more active than I use to be and I’m not taking my antidepressants anymore, yet I’m still gaining weight.

I’ve tried exercise and diet but nothing has made a difference.

I’ve had my thyroid tested and my vitamin levels and everything came back clear.

No one in my family is overweight from a medical reason, not my mother’s side, not my father’s side. In fact, both sides of my family are quite skinny.

I’m at my wits end and I feel like I can’t go on like this anymore 😭

What advice can you give me?
