All three of the listed pursuits are about equally good for you at the moment, I'd say. Just keep doing that for a while. You'll probably start asking yourself how long it's going to go on that way, if you're not already. That means it's working. You'll probably find all sorts of ways to cope, and most of it's not as harmful as it seems. Death isn't going to help, though, given the mutual nonbelieverhood. Self-mutilation is bad too, but I don't see you looking at that either. Otherwise, it's all good harmless fun that you're just in no state to enjoy.

If talking helps, I'm a good talker and a good listener all in one. If not, I was never here and you can't prove anything.
