Plurality, PTSD, sui
I guess some backstory: Chelsea was the host until one of our suicide attempts back in April 2015. We ended up hospitalized for two weeks. She stayed around afterwards but was pretty much a zombie. Our next hospitalization was later that same year, and afterwards, Chelsea "died"/permanently went into hiding. This really traumatized/messed us all up, because none of us knew how to function as a host.
I was later forced to be the host. This came with a lot of problems, obviously. I was forced to deal with the the trauma we had gone through that Chelsea blocked out (I was previously a protector). I also had to fall in love with my wife, because she was Chelsea's wife.
I just always wonder why I was made the host when Erin is obviously the more capable one of us. I may have known Chelsea better, and I know I'm stronger than she was, but Erin is the nicest, most stable of us all.
