If I have multiple mood swings, prove to myself I have split personality disorder due to depression and research online, whats the best way to help with or find out if its what I think? My boyfriends concerned, i have rash depressed moments enough to cause myself pain.. Is there help for this? all i really wish to know is what i may have and what i can do so i dont cry everytime i think of something bad which may happen due to stress or what i BELIVE will or can happen in the near future. Im a 15 year old girl.. maybe this is just normal for all i know. Sometimes i just talk to myself in my mind to stop crying..
