I can relate, therapy can be a challenge, but after a while you will find that you can process it better and accept that it happened and work towards finding your way forward in spite of it. I can't say enough "patience" with this is very important "patience and self care". Also, you don't have to go into details, it's up to you, you will figure out what you need to talk about and what you don't have to talk about.
A good trauma therapist will not push you, instead will want you to feel "safe" so you begin to feel it's ok for you to talk about it.
