I think it's definately possible, I turn to relapsing when I'm hitting rock bottom or feel like things are getting out of control. Truth be told I sometimes even miss the old me when the disorder had such a hold over me I wasn't giving the world much notice to care what was going on around me. It's a horrible vicious cycle to fall back into but yes, I do it also. I just hand over control to the disorder completely in a 'do with me what you will' fashion.
I hope you're doing okay, relapse is a horrible thing.
I don't really feel anything. I just don't care about anything anymore and I just hate everything about myself and everything just seems to be super annoying.
Yes I think it is possible especially if you are feeling low. Can you enlarge on how you are feeling ?
