I find it unfortunate that some people are suffering as a result of this condition and I can certainly understand that if it also involves depersonalization, it could lead to less than fun experiences. I have empathy and feel for you if that is your case. For me, on the other hand, it's the exact opposite and it is the one thing that makes life worth living. I personally truly enjoy the dissociation that my body creates.
When life involves pain & suffering, and when one is confronted to the absurdity of life, what is one supposed to do? Some CTB, some keep suffering either because they can't physically CTB or they choose to endure for whatever reason (for their family, friends, beliefs...), and some find meaning in distracting themselves. Regardless, the pain is still present and it never really goes away. However, the few times when I do not suffer is when my body is dissociating from my thoughts. I live in a dream-like world where I am not fully in control of my environment but, somehow, it is still more pleasant than reality itself. My mind seldom goes to bad places, but more often than not, it ends up in an ideal world where I am actually reasonably happy although it's generally very abstract. It's a little difficult to explain, it's like being in a movie that your mind creates: lots is happening and even though you're not an actual part of the "story", you still enjoy watching as events unfold. When life sucks, any alternative is better, I guess. Similarly, I absolutely enjoy dreaming at night. It's a little bit of a balm for an otherwise shitty life.
Now there are some drawbacks. My memory is getting shittier and shittier and forgetfulness rules my life. It's not uncommon that if I need to run two errands, I do the first one and then somehow end up in a day-dreaming state and completely forget about the other one. At first, I was scared about the repercussions, but I just eventually stopped giving a f... I forget work stuff, meetings with friends and other things but whatever. When it happens, it is the only part of the day that I feel a little less the endless suffering that cripples me as my mind is busy in this "other world". I just stopped giving a s... about the "real" world. The one that my mind created involves much less suffering. And for me, this is as "real" as the other fucked up one.
