I'm having a problem with a ghost.I think that it's the ghost of my sister,I don't think that she's "at piece",in face stuff has been really tense lately,I see all the signs.People who were close sensing her(mom mostly),stuff in her room moved around,and I thought she was here to comfort her,but lately mom seems ultra-depressed and constantly drained.I know how to exorcise her but I cant bring myself to do it.I don't know where they go if i do...ya know?

From what I know ghosts only come back if they have  some kind of unfinished business. You should try to help it move on to the next plane whatever that may be. Just wondering, what is your method you think will work to get rid of the ghost?

Also some more background information may be helpful.

What makes you think it is your sister?
Detailed descriptions of what it is doing? (what is it moving about, time when these things happen etc.)
How long have these events been occurring for?

 There's a good chance that it's not your sister, but just some ghost that wants to be a prick. Just because you're a ghost now, doesn't mean you'll be any different than when you were alive.

I'm thinkin kadesh is right,I only thought it was my sister because she died just a little while ago,but i'm sure she's in heaven or whatever place good people go when they pass.Anyhow everyone around the house is still shaky.I think it's something feeding off of that.All it does is follow my parents around though,I haven't noticed it near me without one of them being around.Lol I don't think it likes me.I'm seriously considering exorcising it.And to answer the your question my method is simply overpowering them and telling them to leave (in the name of god).Is there some sort of like gun or sword or something i can use instead?

 You have the right idea. When I get pissed at something that's let itself into my house, I usually end up stomping my foot. I don't mean to.. they just peas me off.
