PTSD Diagnosis

I recently went to rehab, hopefully concluding 20 years of daily-use addiction. I followed up with a psychiatrist yesterday and found out the dr at rehab diagnosed me with ptsd. I was molested for years as a child, then drugged and raped in college. My mental health has deteriorated over the years, and I knew I had trauma issues, but hearing the Dr tell me I have ptsd made me feel…even more damaged. I don’t know why, I just feel so much worse about myself today. Nobody in my life knows anything about what happened, so there’s nobody to talk to. I guess that’s why I’m venting here. I just want my nightmare to be over, and it feels so much less likely that I will ever feel better now. So disheartening.
