I’ve seen some stuff relating to your question before, and based on what you have described, I would say you have a chance at the priesthood. But, the online community does not make that determination. It’s the bishop that will lay hands on you or not lay hands on you.
As for your fears, I believe you need to trust in God more. Fear is not from God; fear is from the devil. We all have fears. If yours are obsessive, try praying more and develop a daily prayer routine, realize that you should not worry about things outside of your control, pray to St. Dymphna for help with your anxiety and other disorders, replace a bad habit with a good habit (such as prayer) every lent, and pray the simple prayer “Jesus I trust in you”.
