This sounds like classic anxiety symptoms. For me py panic attacks came complete with dizziness, feeling like I couldn't breath, racing heart, etc....total nightmare. I was able to manage them with the occasional Xanax but about a year ago I graduated to general anxiety. After trying to tough it out I finally went to my doc and he put me on Zoloft. After the nasty start-up side effects passed I feel better than I have in years. Have you been to see a doc about your symptoms? If not I would recommend you do so, sometimes meds and/or therapy can make the difference between living in fear and reclaiming your life....I still kick myself for waiting so long to get help. Hang in there!
