Is it worth it??

Ok, so I am going to vent. I don't want this to sound rude or the "poor me" kind of stuff, but I am frustrated, VERY frustrated!! Ok, here it goes. Lately, I have really made the effort to try and reach out to those in my Family as well as certain Friends that are in my life. I am the one who calls to ask them how they are doing, ask them if they want to get together, ect. SO, I was thinking the other Day, and I thought to myself, When was the last time someone called Me to see how I've been and so forth, and very few have done so. Am I really not that important?? I mean, I understand that life gets busy and crazy and that it IS hard to keep close relationships outside of your own Family, But still, I just have felt gipped with certain relationships that have been in my life. So I ask myself, is it worth it? Do I just keep chugging along and make the efforts? Or do I end ties with those that have not been as close with me and move on? It's really hard, because a lot is my Family and i just don't know what to do anymore. Am I the only one who feels this way or what?? Anyways, just thinking...
