I was just reading about the dissociation disorders on http://psychcentral.com/disorders/ As far as I can see nothing you wrote about meets any part of the disorders side of dissociation so my opinion is that its the normal Im bored with my life so for a bit Im going to daydream kind of dissociating. Here the kind of thing you wrote about is called escapism and its normal and not always a bad thing. alot of people who do this end up actually changing their lives for the better by trying to make their daydream of being a better and healthier person a reality and end up being choosy on career moves so they end up in the end with a better healthier life even finacially.

I used to daydream about going to college in the days when it was obviously out of my league to do. my family just wasnt in the place where they could finance my college, the location nearest college might as well been a whole state away because I lived up in the backwoods of the hollers where practically no one leaves. but with the help of my daydreaming I found creative ways to get the education and life that I wanted for myself.

we arent allowed to diagnose people here so you might want to find a psychiatrist and therapist and talk to them and have testing done so you can find out what it is.

but I say keep on dreaming about what you want to be and what you want your life to be and maybe someday you will be able to find the way to be that healthy strong person you dream about being.
