To wish an impossibility is a dream

A dream is a wish your heart makes. That was what Cinderella said. Although she is a smart lady and I would never want to go against her, however she forgot to add that when you wish with your heart, it usually involves impossible things. And because they are impossible, they become a dream that you can only dream about. Hence the name, dream.
There are so many things that I dream about, and all the things that I do dream about, they are an impossibility. They can't happen and I try very hard to wish that it may come true, but it never does. Maybe someday it will, but for now I know very well that it is something impossible and it definitely would not happen. Especially not to me. All this while things have not been what I wanted, what makes me think that this time is going to be any different?
I know that those reading this would be silently killing me now (yeah, I know you guys are) because you would tell me:
1) that it is not impossible; there is a possibility
2) do you have to be so darn negative about it? where's the positivity i taught you?
3) take it slow, there's always a reason to it, and that's why it's just not happening now
4) that it wouldn't be me (i have low self esteem, but I have a good reason to be)
But how sure are you that it could be? That it may be?
Because all this time I thought there was something as well, I mean the signs they were obvious! What more with everything falling into place! But things may not be what I think they may be and that how I may wish for them to turn out to be they may not happen, will not happen, never ever can happen. I fantasize so much about the things that may be, the possibilities, trying to edge in the positiveness in order to provide more good 'chi'. But I end up feeling hurt when the conjured visions do not take place. When will it ever end? I sometimes wonder. Maybe I should never have got involved then there wouldn't be this to worry about. To feel like I gave my all and though you may appreciate it at most times, it feels like I am still under-appreciated. The things that you promised I thought you'd fulfill, and in a way you did, but they weren't enough. Not enough not in the sense that time was the matter, rather the commitment and the show of appreciation and promise that you once made. It feels like I am not that important but at the same time I am. Choose will you??
