Ales - I sympathize with your reluctance to medicate the pain away. My T also suggested using a drug, at least temporarily - so that I could continue to function in my life. She was trying to help with that suggestion but respected a lot of my reasons why I didn't want a reprieve; I wanted to simply face it once and for all and put a stake in the heart of the demons that "haunted" me. I was moving through a lot of intensely painful realizations and memories, pretty quickly. Some days it really WAS overwhelming - but pain is not depression. Grieving, sadness, wishing for what was NOT my experience - is not depression. I didn't take any drugs...
so what we did instead was "pace" the work... I wanted to move full-steam ahead to get through... but my T worked with me to slow down enough to fully digest, address, and let go the worst of the pain about even just parts of some pretty difficult realizations. Keeping a journal let me obsess - intellectually and emotionally - as long as I needed to until things started to make sense and (in most cases) didn't hurt as much anymore. I could scream on paper, with worrying about annoying or upsetting anyone else... I could whine the same laments - over & over - until I decided how to move on. And yes, I'd get up in the middle of the night, go to the journal... and only write down a few words! Then, in the morning, I'd pick up that thread of thought from the new perspective. (And this helped me get past the endless "thinking" or obsessing that sometimes prevents sleep).
Hope this helps.
