I've had it for 25 years. I have DP. I have DR 24/7. I don't know when it turned 24/7. My earliest memory of having is crossing the street to get a basketball and returning back just looking at everything because it looked dreamlike. Now I am 33 years old. I was diagnosed in my mid 20s. It was also determine I don't have PTSD or schizophrenia. I have symptoms of ptsd but not enough to meet the criteria for it. Actually meeting the criteria for ptsd and depersonalization isn't common. According to a book on it only 5% will meet the criteria to be diagnosed for both. The treatment plan I was told would be years of psychotherapy without medication (good, I hate medications and wouldn't take any). The problem is that it's so expensive. It's almost like it's only meant for rich people and none of the ones who specialize in treating dissociative disorders accept insurance to start off with. I don't even have any health insurance. It costs around $150 or more per session.... And it will take years according to the psychologist who diagnosed me and treats dissociative disorders. I even saw another one before her only 2 times because it cost too much. She's the one who told me to get diagnosed first. But she also said the same thing about it taking years of psychotherapy for results. This isn't going to magically go away on its own. As long as I am not receiving treatment for it I will always have it and it was caused by trauma. So I am being realistic about it. I will most likely have this for the rest of my life unless I win the lottery or something. People don't like hearing the truth because they fear it. I am so used to it that I don't even want to get rid of if for having fear of experiencing reality again. But that doesn't mean I don't experience uncomfortable symptoms due to the disorder. I am just more used to it than others.
