Where to work when you have social anxiety and nervousness ?

I guess I’m running away from my problems but that’s not the right thing to do. I don’t know how to tackle my fear and anxiety. It’s ruining my life honestly. I can’t even order food at a restaurant because I feel so damn confused as this anxiety and insecurities take over me. Whenever I communicate I talk so slow and react to other people slow. I’m not fast paced in life. My walking and talking is slow. I can’t seem to be living in present moment of life. Either I’m overwhelmed and ashamed of the past or worried and stressed about the future.
