I truly think you really need outside of yourself Help from a therapist.
The reason I feel so strongly about this is because, someone outside of you that is safe, can pick up all the things your stressed out with and with PTSD you really need someone to help you through. Doing it alone I feel is just way too hard. So my answer is get someone to help you through PTSD. and get you some help from your peers.

Great Question btw, in healing...... Crew
