Hey. You're not alone.
I feel these things sometimes, too. Anxiety, even social anxiety, can have us feeling afraid to approach something because we feel scared. Our brains are wired through evolution to help us avoid pain. Trust issues sometimes come from painful experiences. Trust is hard to give when we have been hurt.
Anxiety can distort our thoughts. I have felt that way too, and the only way I found through it was to say Geronimo! and take the leap. Baby steps. Try first with something small. Something a little bit hard. Not too hard. But a little bit hard. (Say, like a small interest of yours, or a hobby.) And then another one, a little bit harder. Another one after that, just a little bit harder, at your own pace. You can start with a friend or family member you know to be empathetic, that doesn't laugh at anyone when they share something personal. Or, if you have access, you can try with a therapist or counselor.
Also, another thing I found to help was to check limiting beliefs (I can't) and change your language, even if it's just to add "yet." When you tell yourself you can't, your brain believes you.
Bravery isn't the absence of fear. It's being afraid and doing it anyway.
And be kind to yourself if you don't quite get it right away. This is hard work. Overcoming anxiety is hard work. But you've shown up, and you're showing yourself love in this way. Remember that you're human and it's okay to make mistakes. You're learning and growing.
Thank you so much for sharing.
