I don't want to scare you and much less discourage you. I think what you are doing is brave. I am sending you all the courage and best wishes I can. This is for you if it is okay. :hug:
It gave me flashbacks and still does, it was very scary, and they will push you to the edge of your comfort zone. Still I will tell you nothing good can comes easy. It will be very difficult but it is something you need to do.
"what if I don't like it?"
Well if it doesn't work you are in the same position you are in now, but if it does work/help you will begin to heal.
"Will they make me talk about things I have never told anyone?"
They will encourage you to talk about what happened to you, but you won't be made to. Still if they ask you to talk about something don't bite your tongue and clam up. Dig in your feet and be the brave person we all know you are. The mere fact you are seeking treatment makes you brave.
"Who will help me if I fall apart? but most of all what if it isn't the cure it is supposed to be?"
We will help you and anyone else you trust enough to share with. Don't think of therapy like a cure, but a treatment. Believe me we all want a cure but unfortunately a magic pill doesn't exist. It's more like a burn victim. Daily cleaning of wounds and removal of dead tissue, all which are very painful. Still the pain leads to a new beginning in time.
I wrote a poem about my first meeting with my psychologist. It was part of my therapy. Here it is if you want to read it.
Familiar Costume
my trembling hands are concealed
in the secret comfort of my pockets
fingernails claw at covered skin
digging for courage and realism
my feet nervously bounce on the floor
struggling to remain glued in place
itching for a fight or flight response
they search for traction or quick escape
my chest pounds out a steady drum beat
emotions are timidly trying to escape
by breaking through a corporeal bond
trapped in assumed comfort crying for help
my eyes drip out a vision of freedom
seeing narrowly through a disguising mask
shaking hands try to push back in the truth
but serve to resituate a familiar costume
