hey there... welcome to the forum, even though to you it may not be under the most pleasant circumstances..
DID can be very tough, yes, it can be hell even, and i've been there too, not wanting this, not wanting to be seen as crazy, thinking i won't be accepted.. And to some, i am crazy, by some, i am not accepted, but I have finally accepted myself.. ourselves. DID can be a blessing, it is a coping mechanism designed by the mind to find a way to make something that happened more bearable somehow. Maybe you don't know yet why or how, but you can find out if you get to know yourself.
Please don't be afraid of yourself, or of the opinions of those around you. There will be poeple who will love you even if you would tell, there are people who will accept all of you, but first concentrate on trying to cope with yourself and your own mind. As Seangel said, ask questions, look through posts. If it hits close to home, maybe you can do somehing with it, read the advice people have given each other and see if you can use it. To me it helped tremendously to know i wasn't alone and that there were people who had gone through the same and could give me insight on what to do next.
I've been lost in my mind, lost in a whirlwind of depressions and days where I couldn't handle myself and wished it would all stop. it will get better. Those may seem idle words now, but please trust me, it can get better. DID is part of who I am now, I could not have wished for better life-companions than my alters, and they help me cope, protect me and care for me. It doesn't have to be bad
sorry for the long rant

I hope you'll feel better soon.
