One more thought - interestingly, this is one thing (the only) that I can find relief in on my way into a depressed episode - there's a sweet spot for me sometimes where I don't feel anything at all, and it can be such a break from feeling everything all the time. If it lasts for any length of time, though, it starts to get pretty damaging. So I wouldn't glorify the cynicism unnecessarily - I think it's a brief and hollow respite.
