i read it but wasn't feeling safe enough to post at the time ( i hardly ever feel safe enough to post

). anyway just wanted to say that it's not a shameful or embarrasing thing to do (even though you may feel that way). it is simply a way of coping. i would definately talk to t about it. revealing shameful/embarrasing things to t and being accepted anyway can help aleviate those feelings and help improve self worth. plus t can help us identify why the world might be coming back at this point in time (ie help you identify stressors you may not be aware of). also if you would rather utilise different healthy coping strategies, t can help teach you alternative strategies.
i am not able to create imaginary worlds, partly because i'm not that creative - sounds like you are creative which is a brilliant strength to have. but i do remember reading here of others who have - you may like to do keyword searches in the forums to find what others have said in the past.
anyway - hope you can bring it up with your t - talking about it with t can help in so many ways.
