I made it through with no pills, alcohol or psychiatrist, although I'm not saying this would work for everyone. Talking to someone about it would probably be the best option of the three (not necessarily a psychiatrist).
I faded out, so it took some time, and I had time to go through several phases of doubt, coming up with new belief systems, discarding those, researching many things, coming to terms with my mortality (that was the worst for me) and finally accept my "fate". There were some tough 'episodes' in there, but I got over it relatively fast, actually. Since I faded out, my family gradually got used to the idea, and I didn't have to suddenly "out myself" as an apostate in one night. When it finally happened recently that I had to tell them in so many words, it went relatively smoothly.
I'm pretty much a whole other person than I was two, three years ago. So it can be done. Not that I'm 'done' with it completely yet, but... I don't know... 99%?
Good luck whichever way you end up handling it.
