Hi, I'd like to help you with your question.
It sounds like you may have a few different things going on. One, you may have mild social anxiety. Two, you may be introverted in personality. And three, you sound like you have some self esteem issues.
First, social anxiety is a severe anxiety about embarrassing yourself in front of others. Most people with social anxiety go through great lengths to avoid any social situations, particularly if they feel threatened by them. In any situation you feel you might be criticized, judged or watched, you avoid. It is above and beyond the normal nervousness people get in front of others. Here is a link to help you understand social anxiety:
Second, you sound like you might have an introverted personality. An introvert is someone who prefers to avoid social situations in favor of spending time alone. They find socializing very draining and need a lot of time to recuperate when they do socialize. There is nothing wrong with being introverted, it's just a preference.
Third, self esteem issues can interfere with your ability to feel good about yourself. It is the evaluation you give yourself on your own self worth. Most people with self esteem issues learned at one point or another in their lives that they are not as worthwhile as others. It is learned usually from a parent or difficult social situation in childhood.
You may have all of these issues, or just one or two. But either way, resolving these problems is just a matter of determination and a little bit of work on your part. Therapy is a good place to start. But since you have been in therapy and found it not helpful, you may want to consider switching therapists. Try this link to find a new one:
