Lost Friends

So lately I have been thinking that I have lost some of the friends that I so really really wanted to keep in my life. When i say lost i mean I just dont talk to them as much as I use to.. this really bothers me. For the most part they are busy I know that,but at the same time friendships are a suppose to be a 50 50 things. I feel like some of my friends have just left me behind, and it really hurts. For the most part I now that I was busy and always working, and for the most part I am still doing that. But this college life of mine is coming to an end and I dont want to lose those people tho have actually had a positive effect on my life. So if any of you are reading this.. i really do miss you and i dont want to end up not speaking. It really sucks I hate not having you around in my life. When i think about it there is a reason that we are all friends we click somehow.. and believe me it sucks when you click alone.
