Am I Really Psychic

I really need some ones help, I have these vision type experiences where I'll see something, I once saw a friend of mines getting harmed in an accident and it later happened. Sometimes I'll be writing something not really knowing what's happening then I'll read what I've wrote and it'll be something simple like 'Chris will call you, you'll be able to fix things.' later that day or week it'll happen.

That's not all that happens, I've been able to hear peoples thoughts I've heard them say something or well I've thought they've said something but they tell me that they've been thinking it. I'm some how connected to my ex, he was drunk not so long ago and on the night that he got drunk I wasn't with him but I can't remember parts of that night and I've had people tell me that I was so drunk. I'm only 15 and this scares me.

I see spirits all the time I feel like I'm never really alone, I can see them and when I can't see them I sense them being there. I'm not the only one that I know that this happens to, I really have no idea what's going on no one in my family has had this happen to them and I've read that it can be carried through families? Am I psychic or is this just me being young? There are two spirits that I see often they're two little girls one looks just like me and they tell me things about my friends how they're feeling or what they've been thinking and when I ask about it they become so shocked not knowing how on earth I could have know that they were thinking that.

It's the visions that worry me the most, I've seen myself die before and have heard someone saying that I won't make it past my 17th birthday. I don't want to get rid of my powers if I am psychic I just want to know how to deal with them. Thank you.
