anxiety
"After trying a few medications my psychiatrist put me on Paxil. I felt like it DID help with my anxiety and depression but that came with a price -- drowsiness, huge loss of libido, and horrible withdrawal symptoms. I was always lethargic and never wanted to go out and do anything, but I felt less anxiety and depression. I would literally go 7  days without sex (with my partner of 3 years) because I just didn't feel like it and I could definitely feel the negative toll it was taking on our relationship but luckily he stuck with me. After getting fed up with the intense side effects, I quit cold turkey -- huuuuge mistake. I felt like I had the flu and the brain zaps were never ending."
