I'm a broken man and I don't think any woman will ever want me and I'm afraid of what I would do if one did. What is your opinion on this?
I don't think you should think of yourself that way. It's not good to be so overly critical about yourself.
Do you really think that will help? What do I have to do in order to get God to help me?
If it's something you believe in it could be helpful to get you peace of mind and possible motivation to work on these insecurities.
It's going to take awhile. I'm scared that I will hurt someone.
Any baby steps is a step in the right direction. Go as slow as you need, but steady too. You need to watch what your friends do, the most successful ones with the best relationships.
