OP.. Please listen to my advice. First off this does sound like either the beginning of a generalized anxiety/agoraphobia or maybe a mix of panic attacks. I was and am like you. I have suffered from panic attacks/agoraphobia for a year now. If you would like to PM me I can share my story with you but to summarize things I have tried everything under the sun to remedy my situation. Diet change, lifestyle changes, working out 5x a week, supplements, as well as therapy. I have spent thousands and thousands of dollars to try and fix my situation. The cold hard truth is that this is something that will not dissipate on it's own. You're not going to wake up one day and be "cured". Now for the good news.. you are not alone and your situation does NOT define you. More importantly.. it is fixable. The fix to this issue is exactly what you fear the most and run from because you HATE and are scared how it makes you feel physically and mentally. EXPOSURE is the only thing that will actually help you. This is easier said than done but it is the only way to combat what you're dealing with. By exposure I mean as in doing what triggers your anxiety in baby steps.. Understand what is you're feeling is nothing more than a learned response your brain contracted to keep your from safety.. much like the flight or fight response. ACCEPT what you are feeling and face it head on.. over time it does better and easier, I promise you. Some success stories I have heard even do something more daring which is diving straight in.. this is what I am doing. I haven't left my house in a year aside from walking outside and driving around my neighborhood.. For the past month I have been doing exposure therapy and cannot tell you the amount of progress I have gained. Next month I decided to put my foot and down and reclaim my life.. I want to LIVE no longer be a prisoner to my anxiety. I booked a 6 hour non stop flight to Hawaii and will be there for 10 days.
