Does Love have just one meaning?

I have come to realize in the past year that love has more than just one meaning.... I don't mean the love that you have for family or friends... I mean the love that keeps you up all night. The thing that is constantly in your mind weather you know it or not. The love that has you go to any length and do anything just to see that person happy. I have come to realize too, that love like this is rare... what i mean is that regardless the situation, you would love that person without wanting anything in return (no strings attach)... I believe that loving someone in this manner,you make sacrifices for the other persons happiness. I have found this... it amazes me that I just realized how much it means to me that I have that. That I am able to give back with no questions in my heart if what I'm doing is the right thing... I am just very sure of my future and I hope that you whoever you are, have found a love in your life that doesn't make you second guess your feelings. And if you haven't I hope that you do find it and when you do remember to cherish every moment for you never know what the future holds for you....
