Nurseboy,
I remember when you first came to this board, your posts, if you look back over them, you have made significant progress, you may not see it, but its apparent to the ones who read posts, you can see the changes, the strides you make, many times, we were so very much in the complusive stage of worrying that when feeling better, there is almost a sense of this happiness isnt deserving or flat fear that it wont last, hence the down feelings, it takes time to desensitize to feelings, it doesnt happen overnight, we sometimes feel, things have been going so good, your almost anticipating the world crashing down on you again, allow yourself the good days, and remember not to beat yourself up on a down day. You truly have made major strides, this too will pass.
