I'm not sure exactly what is wrong with me. Lately I have been experiencing episodes where: I get really nervous suddenly, my heart begins to race and beat harder than I think it should, my chest begins to feel really hot, and my whole body starts to tingle. I get scared; afraid that i'm going to have a heart attack or something. It is interfering with my performance in school and social activities.
What could this be ? Am I suffering from anxiety? If so, what do I do about it? Is this something else?
I also need to add 2 other things that may be factors : 1. I have anorexia/bulimia and am severely underweight. 2. I am taking antidepressants.
Any help or comments are appreciated.
