how can you be self confident when you have high anxiety problems

Try and push yourself, especially if you don’t want to do it.

Make sure you do it and then you’ll stop staying in the place you feel you are.
You stop yourself from becoming the person you really are, by thinking you’re not anyone.

Your fears stop you from becoming who you are, stop worrying and just be you.

Not really. It's pretty.much impossible to have confidence when you're anxious. I know from personal experience. Just accept it. 🤷

Walk up to strangers and with an outstretched arm, offer a hearty handshake.
