When I open my eyes I feel the huge feeling of panic and worry which keeps me lightheaded. Sometimes it feels as if I am not living but I'm just there. I take Xanax and feel ok for a few hours. Early to mid afternoon I feel awful again almost as bad as waking in morning. Have no choice but to take xanax. Feel giddy , eyes feel slow, lightheaded like crazy, and some head aches or pains. Four months. Wonder if it's MS or something. Would I be blind? My doctor said he would know by urine tests for diabetes because I mentioned it. Tumor.... Or anxiety or something that will go away on it's own I can't figure it outtttttt.
