I’m a horrible friend.

I’ve lost so many friendships in the past years because I am the WORST friend. I lost connection with a group I was super close with out of my own anxiety and stupidity. I have had numerous opportunities to hang out but I always flake last second. Day of I get horrible panic attacks and start to just work myself up over nothing. The idea of leaving my house and being in a bar or even just at a restaurant makes me panic. Sometimes I can do spontaneous stuff or hang out one on one but outside of that it’s a panic attack trying to put my shoes on. I wish so badly I could overcome this and be a good friend again.

Does anyone have any advice to please help me be a better friend ?
