Hi welcome to Psych Central. Sorry you are having a tough time being at the weight you feel comfortable.

I am not a doctor so I cannot say what the problem may be, but a friend with depression had their thyroid tested and it was found to be underactive. They have had to be reevaluated after they started the med for a couple months and were still below the normal range so they had to go to a higher dose. Maybe your medical doctor can have you checked for any condition that may be a contributing factor.
