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.
It is possible that you could have or be developing an anxiety disorder. There isn't really enough information provided here to suggest a particular disorder, but it might be worth meeting with a counselor or therapist to do a formal assessment. Some of the questions they might ask could be what other kinds of physical symptoms you experience, how frequently these physical symptoms happen, what's going on for you when they tend to happen, and how frequently/intensely you find yourself worrying in general.Anxiety itself is a really natural thing - it's just when it starts interfering with your ability to "do life" the way you want that we start to consider potential disorders. It might be that for the most part, the anxiety you feel is normal and you simply have some triggers that intensify it more than usual. Working on your own or with the support of a counselor/therapist to both address those triggers at the root and also to develop ways of managing the actual anxiety symptoms. This two-fold approach can be really helpful for not letting anxiety keep you from engaging in life the way you'd like.
