I agree. Physical pain is easy and so superficial. The emmotional stuff hits down deep and can feel soul shattering. For me it is much harder to cope with emmotional stuff, the feels are just too intense and raw at times.

Guilt, shame, and anger are ones that I have a difficult time with.

Maybe talking about it will help you become at peace with what you did. It is hard to hold on to secrets and they eventual consume you. Making ammends to people is a way to deal with guilt. Showing remorse and trying to make things better. That isn't always possible, but you can try or at the very least acknowledge that you feel bad about something and realise there is nothing you can do to change the past.
