Birth control concerns..?

I just recently got prescribed the BC pill, went and got the prescription, but now I'm having some serious second thoughts on taking it. I'm worried it will worsen my depression, kill my already devastatingly low sex drive, amongst other things. I've already addressed my concerns to my doctor but I'm not convinced by her AT ALL. She doesn't seem to care about my concerns. What should I do...? I need to take it tonight if I'm going to take it
