Hi everyone

Im new on the board and I would like to share my story and see if anyone has had the same and could offer some advice/encouragement.
Im 25 years old and have always been heavier, not very overweight but always curvy.
3 years ago I went on the Anti-Depressant Wellbutrin and I experienced dramatic weight gain. Now I don't blame the meds for all of the weight gain, I know I have not been eating well. But it seems even when I try and lose weight, nothing happens so I quickly give up.
Over all I have gained about 25 pounds, ending up at 165.
The big problem is the medicine is helping with the depression, but now with the weight gain, Im even more depressed than when I started the meds.
Has anyone else experience difficulties losing weight due to medications and quickly giving up hope?
Any motivation or words of encouragement would help.
Thank you
