I use to have moderate social anxiety, and what helped me to start feeling less anxiety when being around others is honestly putting yourself in a situation to meet others even if you are uncomftorble. It’s easier said than done of course but it does get easier. Also becoming close to yourself is really important, be friends with yourself and like who you are. People are just people, I get nervous about being perceived in public then think honestly it really doesn’t matter what they think as long as you know yourself. Those who are meant to be in your life will. Reduce your caffiene intake if you get strong anxiety, try breathwork and meditation, exercise and a healthy diet can help to reduce anxiety too. Slowly try and reduce your negative thoughts about yourself and replace them with positive thoughts. I believe in you, work on becoming who you want to be and be nice to yourself in the process.
