I talk to my dog (literally), when I haven't got a bung ankle (like at the moment), I'll go for a walk. I avoid total disassociation by just getting something to eat, a second hand novel and just sitting somewhere where there are a lot of people, like a shopping center, and just watching interaction from the safety of the sideline. I also accept it when I cannot concentrate (took me a long time to do that), you cannot force it, you cannot fake it, you just have to accept it (and for some reason it takes less time, or seems to, before you can). When I get bad, I actually write gibberish and believe it is good work, it sucks but this crap is so sneaky it is amazing.
