I want to be a better friend!

I don't know why, but lately I have been thinking about all the people that I have lost touch with over the years. I had some pretty rockin' friendships in the past and I'm not sure why they went by the wayside. Could it be the new social media platforms that are always so "in your face" that I feel like I'm keeping track of them without actually having any interaction?

Is there a good way to be able to reach out to a number of people? Should I send a weekly update? Should I just try to email people personally more?

What am I trying to gain from this? I feel like it might be that I just want more friends in my life. Yes, I got married and basically have lived in a hole with my husband for the past 4 years. He is now fully engrossed in school and all that entails, so I am a little bored and lonely, although I don't think that is the correct word in this situation. I need some friendly enrichment!
