know the feeling?

I really dont know d feeling. When you know that you want something really bad and dont really know why, that's d feelin I get. Its so irritatin and wont get off my mind. I guess I find it hard to trust the person. But I dont understand why I am being so emotional suddenly. I am being extremely unfriendly. Maybe its d fear dat we might not be able to live our lives together. But dat has not bothered me in d past. I feel good and bad at d same time. I feel good cos I know how much I can love someone. And bad becos d person had changd so much. I know its cos of me. And dats all d more frustratin. I am afraid dat he might start seeing someone else. Or worst still, start dislikin me.
