I've been having problems with socializing recently. I am having a hard time talking to most of my friends. Everytime I come home from school I am feeling so tired that I can't even speak to my parents. I have panic attacks. I overthink almost my every action thinking about other people's opinions on it. I am also in love with a girl and I can't tell her about my feelings. After some time I realized I actually have anxiety. I want to be different but I don't succeed. I wasn't like that just a few months ago and it really confuses me. Please give advice.
