Birth control symptoms

I started BC about a week and a half ago and I'm already starting to feel terrible. I've gained a few pounds and I'm extremely depressed. I have a history of depression but I don't even want to leave my room and I cry every day. Any one else experience this? Does it get better once you get used to it? I really don't want to stick it out at this point. I feel so huge and my increased appetite hasn't been helping. I just really don't know what to do and any guidance would be helpful.
