Sometimes, I'm fine and can go out or meet people, but other days, my heart races and words physically cannot come out of my mouth. I've always thought it was normal and I was just nervous, but the other day, it took me almost 30 minutes of sitting in my car to find the courage to enter Target by myself.
Do I have some type of anxiety?
I would suggest keeping a log of those days when you are having a hard time. Items to write would be what were you doing before you felt this way, did you eat and what, what time of day is it, how much sleep did you get that night, etc... This can help you identify any triggers. Further assessment can be made by a health care professional. It does sound like you are experiencing some symptoms of anxiety.
