I have PTSD but have not been in treatment "specifically" for this as I have other issues and they all just kind of melded together and we worked on the specific symptoms.

One thing I would like to point out is that you are older now and will have more control over what you contribute to the treatment. You will not have your mother "hovering" over you nor will there be a psychiatrist writing prescriptions that you do not want to take. You always have the right to refuse to take any medication that is recommended to you if it does not seem like the right thing for you to do (although medication can be an important part of therapy when done correctly). You will have the opportunity to build a trust with the counselor gradually and talk about things when you are ready to talk about them. Communicating this to the counselor is important and he/she should know that talking about any traumatic even is difficult and should not be forced.

I can only say to you from my own experience that my PTSD did not go away easily. I could reason things away but needed a lot of help with the emotional attachment to them. I am actually still working on the emotional part.

I would say give it a try. If it makes you uncomfortable, you can always say "enough".
