Any good doctors looking for a Challenge? (revised :D)?

I am not a doctor, however my friends sister had similar problems with fatigue, headaches, a horrible immune system and seeing things and it turned out to be a valve in her heart that hadn't closed properly. You may want to go in for a cardiogram since the mri didn't show anything too unusual in your brain. Hallucinations may be from the medications you are on. ask your doctor, they may switch them. Thats the only idea that i had, i am sorry that you feel so crappy, i hope that you feel better and find out what this is!
