Fear is crippling your life. You’ve already dropped out of college. You can’t make friends and you could not even go pick up a prize at a local radio station. This problem has become out of control. I would advise against handling this problem on your own. I would suggest that you strongly consider seeking professional help for this issue.
You are afraid of people judging you. You are afraid of what people might think of you if you were to make a mistake. You are scared of people looking at you in the gym. You also said that you were too afraid to attend your college classes because of your fear of what the teacher might think of you if you didn’t have a good answer. This problem seems related to how you perceive others are viewing you. Your fear regarding others and what they will think of you is disrupting your life.
Essentially you’re sacrificing your life because of other people. The people you are worried about judging you are random people. They are not even people you know. Do you really want to live your life always concerned with what other people think of you? Do you realize that people who are relatively unimportant in your life, are effectively ruling your life? In other words you are letting others determine the course of your life. This is not how you should live.
Therapy can help correct this problem. If you are willing to attend counseling and seriously put in the effort to tackle this problem you will likely have success. This issue is fundamentally about you not believing in yourself and caring too much about what other people think of you. You will never be happy if you are constantly living for others or trying to please them. It’s important that you correct this problem because it is out of control and it’s degrading your life. Go to counseling and get your life back. Please consider writing back in the future if you decide to attend counseling and let me know how you are doing.
