A brief explanation of what selfshipping is: you have relationships with fictional characters, either as yourself or through as self insert character. These relationships can be romantic, platonic, familial...anything!
My selfshipping, personally, is extremely affected by my psychosis. I'm not ashamed of this in the slightest, though it can make things difficult at times. I consider my relationships with my romantic and qpp f/os (fictional others, for the unaquainted) to be just as real as any real life relationships I may have! I believe my f/os to be lovers I have in other universes, though I can still love them just the same from here in mine :o) (These other universes feel very real to me, as well. I sometimes feel as though I get "memories" from those timelines.)
