Dear Nikolai,
as you know it is contrary to the rules for me to give you advice about your condition. But, given that I have all of the disorders that you mention, and more, I can talk about myself.
For years I did not know what was wrong with me or how to cope. I had been convinced that I had an illness and that there was nothing I could do except take medication.
I took medication but it never worked for me, not on its own. I decided to go to therapy and really listen to my therapist's advise to review my life and think of my childhood. Had there been any problems such as trauma? I did this and found that slowly slowly I was on the road to recovery. The moods and symptoms were there but I could function well because my psyche was no longer aching, my sould was being repaired, my consciousness was being cleaned of all that poison that stays inside and causes havoc.
I don't know about your condition, and therefore I cannot speak of it, but if you have endured trauma of any kind, or if something happened in your past to traumatise you, that is PTSD and, just like in my case, it would not hurt to find out if this is the real problem. Medication alone could not help me more than suppress everything temporarily. For Post Traumatic Stree Disorder Therapy was really good for me. But it is difficult, painful and takes a lot fo courage to go back and revisit traumatic experiences. But in the end well worth it.
