Help!!!!

So I know this isn't a doctors site, but I am having so many issues that I need help with.

1. Ever since I have been put on Effexor for depression and anxiety I have no motivation and can not get out of bed. Should I get off all depression meds or switch meds?

2. I was in BC for 8 years.. I got off for six months, gained weight, got high cholesterol, ovary pain was increased, and I got acne everywhere.. so my friend said it might be pcos, in which BC helps with.. so to avoid tests from the doctor I just got back in BC.. now that I am back on I am still having issues but different types, I have a pain right by my belly button that I have to pinch to get it to go away. I am spotting a lot. I spotted for 4 days very heavily and still have 5 days til my period (we will see if I spot the rest of the next 5 days). My breasts are so so so sore, where I almost cry if pressure is put on them. My back pain is ridiculous. I was nauseous for a week straight about a week and a half ago (during ovulation). Sometimes I spot in the middle of the cycle. I always have pain where my ovaries are. I am so tired all the time (may be from Effexor). I just can't take feeling like shit every single day anymore.. please give opinions and tips.
