Isn't that a song we all know! It's okay to feel anxious bro, the important thing is to acknowledge how you feel so these things can get pulled out into the light where you can work on them.
Maybe your fear of never meeting someone you will want in that way has something to do with your feelings about trust. It's not easy to trust again, that's for sure. But it's all a part of our growth and I'm sure you will get there Mark. But again, acknowledging what we fear is the first step towards facing and resolving those fears.
Nobody living can ever stop me
As I go walking my freedom highway.
Nobody living can make me turn back:
This land was made for you and me. (Woody Guthrie)
