Anxiety...back off, would you please!!!

I feel that there is a cage in which my heart is trapped. Anxiety makes me feel such a big weight on my chest, like there is a an evil stanger hugging me to death, restricting my hability to breathe. I don’t reach for my friends, I don’t talk with anyone ...somehow I think that if I overthink just enough I will finally find the answer to cure this anxiety, maybe that isn’t the way, maybe I do need to reach for help. The problem is I have never felt that there is a safe place for me, I have never felt at home
