Subconcious symptoms and conditions

I need some help. I have been on Yasmin for almost 4 years. Previously I was on ortho and was taken off of it due to an alarming weight gain and emotional side effects. Yasmin seemed GREAT until now... I am experiencing severe anxiety, shaking, headaches, blurred vision, hair loss, low sex drive and depression. I assumed this was all due to stress from graduating and entering the working world, but I have nothing to be upset or stressed about... I have such nervous thoughts and can sometimes say things that are just so unlike me.. I just don't feel myself. I am afraid to go off Yasmin and onto another pill in fear that things could get even worse... My previous experience with ortho was short but definitely not sweet. I am scared and afraid because I am only 22... Has anyone experienced anything like this that can give me some piece of mind?
