Dear BrokenLearningHealing.
Memories that seem to flood you can be very intense and scary. Can you call your T and explain that this is something that has come on full force and you are unable to cope?
As for memories that all of a sudden show up, in the forum of flashbacks, it is a part of healing. You remember them when your ready to deal with them, therefore heal. Doesn't seem like part of the healing process but it is. I know it's hard, believe me.
I don't get flashbacks in the form that you maybe expierencing when I get flashbacks about the abuse, rape, assualts etc they come in the form of body memories. Which is also a flashback, and I didn't know that until a year or so ago. So I can relate. I get triggers all the time that will bring up the past. Like for today for example, I watch a movie and it just triggered me so badly, but yet even though I wanted to cover my face I still felt compelled to watch it.
There are some good books out there that help deal with abuse issues etc, and memories.
I've got 2 books that have helped tremendously, i'd be happy to give you the authors if you are interested?
Hang in there my friend, I know it's hard but it will get better, it did with me. I'm sorry you are going through this.
I'm here if you need to talk.
