I encourage you to go into therapy and tell them everything, exactly how you are feeling. If you don't want to admit something, tell them anyway, including the fact that you really don't want to. You need to tell them everything so they can help, they can be part of your team, they can be on your side.
Are you on any medications? Sometimes meds can cause nightmares for some of us, I have to be careful for instance of Benadryl.
I have nightmares, they have lessened some over time and lots of therapy.
What are some things you can do to help you feel nurtured and cared for?

Best wishes to you.
