Pale.emperor, your OP really struck a chord with me.
I recently started to wake up to TTTATT also. It happened mainly through WT sources, then seeing the list in Steve Hassan's book, of characteristics of mind-controlling cults.
The grief was sharp and deep when I realized I had believed lies. I cried inconsolably for an entire night. It was exactly the same as earlier times, when my mother died, then when my father died. On all three occasions, I felt much better the next day. My way of releasing the pain was to cry like a baby, even though I am a grown man. The pain came out as tears and sweat.
After that, my depression gradually lifted, with the help of some kind people here. It is hard for awhile, but I can assure you that things get better. I am work in process, but I feel good being mentally free.
