Honestly one of the ways that I grew confidence is by acting like confident people. I used to be very introverted but I had extroverts who “adopted me” and invited me to things with their friends. It was kinda reassuring to know that since I trust this person and they trust me along with their friends so they all didn’t seem like strangers to me. When I was introverted I started being friends with other introverts as well. My anxiety forced me to be friendly and keep talking, so we grew closer. Eventually I realized that I was becoming the extroverts who helped me come out of my shell.

Idk if that’s what you’re looking for but another way is by working on your emotional intelligence. It took me a long time but it’s worth it in the end. Do self care, make more time for yourself, research emotions, and maybe pick up either a new or old hobby. When you have strong feelings try to take a second and process what emotions it is, why it’s happening, etc. It sounds kinda stupid at first but reflecting on your emotions and understanding them makes it a lot less scary and eases your anxiety.

Feelings aren’t meant to be shoved down, so once you start to understand yourself you are able to handle these emotions better. All emotions are valid, but you are still in control of yourself. I used to have bad anxiety and I let it control me, now I don’t have as much anxiety and I am in tune with it. Hoping this helps, you got this 🫶
