My mom took me to the doctor a few weeks ago because I was having a few problems and I thought I was about to die. My heart would be racing for practically no reason and I felt almost sort of weak but not really, so of course my brain was thinking "ok we're dying". After asking my mother to take me to the hospital many times she finally gave in and didn't take me to the hospital but a private doctor. When we got there they checked everything and said I was fine. There must of been something wrong because the doctor then asked for my mom and I said "okay just tell me I have three days left to live" in a sort of joking manner and the doctor started asking me about my home life and how I'm doing. I didn't even tell her much and already she knew something was wrong. After a small process of trying to have a conversation while sweating in a room with ac and constantly fidgeting the doctor then called in my mom and explained what's going on. Then after she said what I wanted to say to my mom my bum ass had an anxiety attack. I kept trying to leave cause I didn't want them seeing me cry or judging me for doing this for almost no reason but then after I calmed down no less than 2 minutes later I had another one but it wasn't as bad. 

After that process the doctor set up an appointment for me this Thursday to visit a psychiatrist for Anxiety disorder and now I'm scared. What should I do?
