feeling forgotten

I know I have a great family. And I have some pretty good friends.
I don't have a lot of friends, but the ones I do have I would like to say they are pretty good.
Recently I have lost a few and I miss talking to them.
I have been trying to talk to and/or hangout with one that I hvnt' seen in awhile and I have truly missed having that person to talk to.
But with my schedule and theirs it seems to mess things up.
This weekend we were supposed to hangout but they had "over booked" the weekend a lil and it looks like we have to reschedule.
I am not mad at that person. But I am disappointed.
Because of the reasoning.
I hate that I have to miss out on things.
I miss out on a lot.
I see my younger sister seeing the world. Able to do what she has always thought of doing and expanding her life's adventure.
I see my older sister buying a new car, a new house, getting married and able to go out to do things like concerts, parties and what not.
Why can't life be easier for me?
All I have needed was some friend time. Some time to make myself feel human again.
I wish I could be selfish.
I wish things could just come to me just as easy.
The weekend plan thing isn't a horrible thing. And I can't wait to hangout with that friend.
But this has hit a "nerve" or "sensitive" spot that has been growing inside of me for awhile now.
It just sucks.
