I have had anxiety since I was 12. I am 26 now. I am currently taking Paxil CR 12.5 mg for it. I been on it since January 9, 2008. (I took it before this as well, 3 years ago.) I get these bad headaches, and I feel lightheaded as well, like dizzy, and my legs feel weak, and I am terrified to pass out. Can I pass out from being lightheaded or having a headache? I was told this is all anxiety, but I just want to make sure. All responses are much appreciated. I am very happy to have found this forum group, because I never knew so many people with the same anxiety issues actually existed. I thought I was the only one. Thanks in advance.
