hi I have a question I am 26 years old and for the past 8 months or so I have been having these spells, I have talked to friends and family about this and everyone seems to think because of my history I am having a panic attack. I have been told when I was younger that I am manic depressant, I have ptsd, and bipolar. my symptons are lightheadness, fast heart beats, feeling of choking or can not breath, dizziness, I get hot and sweat, feeling of weakness, fear, tingling in hands and feet, sometimes my eye or cheek will twitch, and ill get nervous and sometimes angery. I have been to the er over this and had blood, pee, and kidney test done and they was fine, my doctor also checked my sugar in my blood and it was fine. im stuck and tired of feeling like this and not knowing why or whats going on with me HELP!
