I would say go to counseling if you can afford it.
You need someone to help you process through all the difficult feelings.
My counselor is working with me on some CBT to help with anxiety.
It feels good knowing that once a week someone is going to be focused on talking with me. It's helpful as a good reality check, too. You can get feedback that you AREN'T crazy, or yes, maybe your perception is bit skewed.
Good luck with all of this.
