You will let go when you are ready-
Remember you are in control of your emotions.
I think outpatient therapy will be good- it will allow you to challenge your thoughts, explain to a neutral person what happened and how you feel. and he or she will be able to give you a guid to get you through this.
No one can say, what is normal, and what is not normal, everyone is different,everyone handles pain differently.
Hang in there, check out the therapy and come here, read other threads, it helps a lot.
