Hey there, I also had sever dp/ dr at 15. I was at work and had a panic Attack and after that it got worse and worse. My life felt not real i didn't recognise myself no one around me, my memory didn't work or nothing. I was terrified and didn't understand what was happening. I had it 24/7 especially right before I fell asleep. I thought I was getting schizophrenia and it terrified me. I could feel no emotion, you could tell me my mum died and I couldn't feel nothing at all. I was scared i had no control over my actions like if I went for a walk I was scared I might accodently walk in front of a truck or something. All I did was think about it and google it when I was awake from the second I woke up to the second I fell asleep, which was what was feeding it and keeping it there. I was running out of options, I was gonna kill myself. I felt insane , I had no hope of it ever going away and I would of rather died then live my life like that forever. I went to the hospital to try and get answers, I was sent to a mental place for 9 days involuntary which I felt at the time was the worst thing and only made my frustration and hopelessness worse. I was diagnosed with anxiety and hyperthyroidism and told that was the cause of it. I didn't beleive it or bother to listen I just wanted to get out of there. Once I got out I was no closer to getting better then when I went in, if not worse. I was hopeless and at a dead end so I did what they told me even though I had no hope of it working. Over coming depersonalisation was the HARDEST thing I have ever done. Oh my God. I had to completely change my thought pattern, and my God, was this by far the hardest thing I've ever had to do. I stopped googling it. I stopped thinking about it. I made myself beleive it would get better, I focused on myself and myself only. On what made me happy. I started colouring in and writing positive notes only. I completely cut negativity out of my thought pattern and I promise you this is the only way to do it. I told myself I don't care if I love like this forever and I kid you not, everyday I felt more real and alive, until one day it was completely gone and I didn't even notice. I prayed to God so hard I changed my mind and that, was so hard. But it WORKED 8 months later and I haven't felt dissociation since. It's a long long road, but you have got to have hope. I'm now 16 and couldn't be happier. I wish you the best! :)
