depression
"People either love Effexor or hate it.  I am on the side of adoration. I am 18 years old and have been taking Effexor for 4 years and the change I experienced was amazing.  I have a long family history of depression and a generalized anxiety disorder, and it doesn't help when you're trying to go through puberty and are constantly being told that everybody your age is going through the same thing.  The side effects are not pleasant, I used to get headaches, my blood pressure increased (but with exercise it can be managed), and get lightheaded and faint more often.  Even with these, I still am happy and am grateful for Effexor."
