I need to talk to a "real" psychic please. Some one just told me i have a negative force that had passed down to me. That's the reason why I fail at everything I do. I would get really close and fail the next second. I need to talk to someone for second opinion.

She said if i don't work on getting rid of this negative force I will be have bad luck in love (even if I find the most perfect man the negative force will cause the relationship to sour).

IS there any one who is a psychic or know any thing about psychic please help me

I don't understand how to answer the following questions:
x^2 = x + 6
Answer: x = 3 or -2

x^2 = 3x + 70
Answer: x = 10 or -7

x^2 + 12 = 7x
Answer: x = 3 or 4

2x^2 + 2 = 5x
Answer: x = 1/2 or 2

3x^2 + 17x + 20 = 0
Answer: x = -4 or -5/3

2x^2 + 5 = 11x
Answer: x = 1/2 or 5

3x^2 + 13x + 4 = 0
Answer: -1/3 or -4

2x^2 + 17x = 9
Answer: x = 1/2 or -9

3x^2 + 2x = 8
Answer: x = 4/3 or -2

when activated somehow. You also somehow figured out how to control it.

Would you hand it over to authorities or what?

Like I said, no units are given. It says it's going by the size of the "relative IP's", which I have no clue what that means exactly. We are supposed to provide answers for the elements X and Y. I'd appreciate any help!

X - 350 > 790 > 1250 > 14400 > 19250 > 3200
Y - 200 > 450 > 800 > 12500 > 15750 > 28500

I usually like keeping my stuff in order in my room, and I usually work hard for alot of the things I own.

An example would have to be a little game system I bought for myself a few months ago.

Now the thing I am upset with is that before this weekend, my family and I took off to vacation out of town, and we left my cousin in charge of the house. She had some visitors over, and were in my room, playing with my belongings.

Before I left, I left my portable black Nintendo DS Lite system in my room. Since I thought it wasn't necessary taking it with me.

But before that, my brother was playing with it on Thanksgiving, and I don't remember where he put it in my room, before I remember putting it somewhere, before taking part in Black Friday that early morning.

When I returned this weekend, I found that it was missing, and I don't know if I placed it in my room or not, and I can't find it anywhere in my house, at all. And I'm really suspicious if her friend took it or not, seeing that I can't trust the people she had over. Or if my brother or I missplaced it.

I just want to know if there is a possibility if I can find hints where its whereabouts may be. Cuz I'm really sick of losing the things I work very hard for, to end up going down the drain.
