anti depressants?

Maybe this don't belong here. But do anti depressants make you gain weight? My doctor prescribed me a low dose of them but I read up on it and a lot of women gain weight. I do not want to gain weight as I just lost 35 pounds! If I watch what I eat, I should be ok? I heard it just increase your appetite? Anyone have info on this?
I posted anon cause I don't want anyone knowing I'm taking this :(
