Dissociative disorder is not about split personalities. Dissociating is when you drive from a to b and you have no memory about the trip because you were singing to the radio or lost in your own interior workings. Or you've read something six times and still can't remember anything about it. Everyone has episodes to some degree and with the depression and dwelling on the past it is only natural to do it more often. While its something to mention to your doc I think dealing with the depression should probably come first.

I second what others have said about the medication and would also like to mention that for some people it takes a great many tries to find the correct combination and dose of antidepressants. It can be frustrating but on the bright side at least they seem to help for a bit

I can't give much advise on whether or not to talk to your boyfriend when you are feeling down. Every relationship has its own dynamics and what works for me and my wife may not work for you. I would suggest asking him however what he feels.

Thank you for taking the time to let us know how you feel and I hope you feel better again soon.
