So bassically, I have emotional mood swings, right now I may be happy/optimistic in my character. Tomorrow/somewhen in the future I may be sad/negative/weak/ any kind of different emotion, and I can allready tell, sooner or later i will emotionally change once again for the 1000th time. However my personality doesn't get effected by it, for example I may inside just feel/be like a completely different person than what my character outside may say, and my character more often than not  usually stays the same, but inside I feel like a completely different person, my mood swings don't happen like everyday, but every now and then, and when they hit, they can HIT. I read that however BPD effects the personallity aswell, am I bpd? I honestly don't even know what I want, and I allready know, as soon as I may know it, I will allready change again.. I don't even know if anything i write makes any sense nor do I even know who I am, all I know is is that I'm confused with changing emotion and a bunch of confusion.
