list of symptoms please read..............?

ok so i have asked a lot of questions regarding anxiety. But the anxiety treatments don't seem to be helping. I am not on any prescriptions at all and for the anxiety i have been to a doc who has done breathing and relaxation excercises these seem to work for a while and then it comes back so i am starting to wonder if this is anxeity if anyone has experienced any of this please help. I will feel normal and then all of the sudden i will be hit with a feeling of being shaky,weak,lightheaded and my head will also feel somewhat heavy,and while i feel light headed i also feel like there is a lot of blood in my head,nauseous,lumpy feeling in throat,heart tremors and starting today i had an intense burning feeling in my chest it lasted for about 3 mins like a very strong heartburn and this caused me to become paniky. I also will sometimes have a weird bitterish bloodish taste in my mouth and feel extremly thirsty and nothing i drink will really help. I also feel less energetic and sore in my neck and back a lot more.I will also get either really cold or hot during this and then sometimes feel like i will have loose stools after them but don't i have had blood done to test for my thyroid and anemia but everything was normal. So like i said i've been seeing someone for anxeity but I have lived with this for three months and it just seems to get worse. I can aslo feel kinda cramped in my stomach someimes with it too. I am not on ANY meds. and until three months ago was completely happy normal peppy etc. I am just the opposite now and sometimes i just feel like crying because life has just seemed to loose a lot with this so now i am worried about maybe i am depressed. I dunno what could be causing any of this but if anyone out there has had anything similar or knows anything please help! I am going to see the doc again tomorrow about my panic but i just want to know if any one knows anything before then! thank you soooo much!!!!!!!
