- How many sessions is typical?
It depends on the person and his/her kind of trauma. I personally had to go through 50 sessions all together (including the open up process and everything in between)
- I've read that some therapists do tapping but I am weird about people touching me...is this an optional thing?
There are two other ways for EMDR to be done. the auditory stimulus as well as the visual one. They usually ask you if you before whichever they chose, on whether you are comfortable with it or now and see what would be the best way for you.
- Do things get worse before they get better?
Things do get difficult and worse before they get better, because you'd have to face and walk through the trauma all over again. you'd find yourself describing things and giving details that you've up to that moment blocked somewhere in your memory. But when that difficult period is over, things do get better, you feel yourself much lighter and stronger (that was at least my case), I hope it shall be the same for you.
- Do you have to tell all the details of what happened during your trauma (for me it's sexual assault)?
The therapist will be asking you various questions about your experience, it does get into details, but the good thing is that you can always stop whenever you feel uncomfortable and decide to have a break or not continue on that line.
Everything stated here are of my own experience and how my sessions went, I hope you find it helpful, and perhaps find more accurate answers.
I wish you all the best of luck.
