Jealousy

Is it still jealousy if you are jealous because you can't do something good for someone? I mean, okay. I guess I will admit it. I am feeling jealous lately because I can't be there for someone I love, and someone else can. There is a part of me that is really happy that my friend has someone to be there during hard times and such. But I want to be that person and I can't. Not because I don't have the capability, but because no one is supposed to know just how much I care about this person. It kinda sucks. That's all I really have to say. I guess I needed some sort of confessional.
