fitness and mental illness

Hi,
I used to write here a lot in 2012...Back then I was hot, motivated and a totally different person. Many things happened since then. 3 months ago I was diagnosed with a very serious mental disease. 6 months ago I had a thrombus in my leg. So I am on meds...I smoke...I gained the 30 kg I lost with such effort in the beginning of 2017 (after my 1st psychosis I gained 30kg as well and I couldn't lose them for 3 years). My psychiatrist says I will be fine, I will lose the weight. I am afraid I don't believe her anymore - I think she says this as if I am a kid, to calm me down. I've been trying different nutrition plans, exercising...I can't hold myself from binges. On top of that I am unemployed.
Enough whining. Facts are facts.
What I wanted to ask is if somebody had the same issues...Or if you know someone who had them...Someone who really managed a situation like mine. Because frankly I will turn into a Kung Fu Panda! My will power is depleted.
Or is it true....that people with mental illness can't lose weight....:(
