Having a dissociative disorder, especially MPD/DID, is like having extreme attention-deficit disorder. I have learned that my whole attitude, emotions, beliefs, etc. can simply change because I switched into these other states, personalities, etc. Switching can cause me not to love a significant other as much as I originally did. It can cause me to not be interested in something, like a job, as much as I originally did. It causes my whole outlook to change. It is the switching and the emotional instability that causes me to not be able to have intimate relationships. I hate it. There is no emotional stability.
