Missing People

Hey All,
Lately, I've been thinking a lot about all of the people I miss. The people who have, for some reason, drifted out of my life. We all have these people, it is virtually impossible to keep in touch with everyone through out our lives, even with Facebook. But it still really stinks when you realize that you no longer have the relationship that you used to have with someone.
I went to a private high school, so when I changed schools, I left behind a lot of middle school friends. I have managed to keep in touch with two of them. Then, when I graduated high school, I have kept in touch with about two people from there. Now, even though I am still in school with these people, I find myself drifting off during the summer. It is just so hard to make that effort. It's not like writing the message or picking up the phone is hard, it's knowing what to say and how to say it.
You don't know what you mean to this person anymore. You don't want to seem too comfortable, or too awkward. Sometimes you don't even have anything to say but "Hi!" but you feel that saying only that is not enough. I don't know if all of this is just me, or if others feel this way. But all I do know is that it stinks.
Not only do I have these former school friends, but I have friends I have met online or at camps or during programs. People from camps you know you are leaving, and you all tell each other "Keep in touch!" But few do. These people, you may have only known for a week, so it feels even weirder to reach out after a long time.
Then you have the people you were super close to. The people you feel guilty about not keeping in touch with. So you don't contact them because you feel bad, and then you put more time between you, and it just becomes a viscous cycle. These are the people I have specifically been thinking off lately. I see them post on Tumblr or on Facebook and I just want to scream "Come back to me!" but I don't know how. I hate losing friends. Well, in a way I haven't lost them, I'm sure these people would be here for me if I needed them. I know I would be there for them.
I guess what I'm saying is that I don't know how to reach out to people I miss or want to contact again. Maybe I'm just socially awkward, maybe they don't like me anymore, or maybe they are having the same problem. So I'm going to try and reach out more, because I want to. And I think you guys should to.
Much Love,
Jenna
