The feeling of being alone is really goo

The feeling of being alone is really good. Although I don't crave loneliness, I really enjoy it. In the past, I wanted to get the attention of others very much, but I found that being noticed by others is really uncomfortable and tiring. Only when I am alone can I dare to express my true thoughts. I don't know what's wrong with me. Can anyone tell me what's wrong? Thank you!
