Hi Therisa,
Welcome to the forum!
My dad is also transgendered (post-op). It is a long, difficult journey. My dad buried his feelings for a very long time and endured a great deal of depression and anxiety. Post-op my father is a much, much happier person and finally feels whole. I am very protective of my dad and I would rather not post too much of his personal journey here. I am on this forum as a supporter. I have friends and a couple of family members who have PTSD (combat related). I may not be able to relate to your experiences of PTSD but please do feel free to message me if you have any questions or need someone to talk to. I love my dad and fully support him. (Pronouns are still a little tricky for us but we are getting there! :))
I hope that you are able to find the love and support that you deserve!
