Defently something in my house.. Ghost or demon?

I am sorry ur going thru this alone. Things like this r difficult for ppl to believe until something happens to them. Some of the sounds u hear r likely to be nothing more than house sounds, settling and pipes knocking, ect...Its not unusual for something to target a person ur age, especially a girl. I know its hard, but u have to try and get ur fear under control, it feeds off it and grows stronger. Do u believe in God? If so, pray for protection and peace from this thing. Ask God to remove it from ur home. Then steadily ignore it. Do not acknowlege it or try and communicate in anyway. If it doesnt get better or worsens, I suggest u speak with clergy. And again, get ur fear under control, it hasnt done anything more than scare u and probably cant. good luck and if i can help in anyway, please feel free to messege me. Oh ya, and whatever u do, leave the ouja boards alone. they r dangerous and can make things much much worse. Can i suggest u have ur mom read this post? She may take u a little more seriously if she see's what ur going thru all in writting
