<human>: Can you give me a shortened version of the text?

Hey everyone, just have what might seem like a silly question about some old friends from high school and various jobs I have had. This site helped me a lot a few years ago with a relationship issue, so I thought everyone could maybe give me their opinion on another matter.

My final year of high school and a couple years after, I was a jerk. A lot of close friendships ended because I was immature and couldn't have a serious talk to save my life. I really don't want to get into all the details, but it consists mostly of me just ignoring these people until they stopped trying to keep the friendship going.

I really just want everyone's opinion on apologizing. At this point in life I am back in school and am quite happy. I have quite a great group of friends, and learning from my mistakes I try my hardest to be the best friend I can be to them. But I still think about all these people from my past who did not deserve to be treated the way they were. I have been recently going through my Facebook and clearing out all the people who I have no idea why I added, and have come to these old friends. I decided I would type up these apologies, explaining why I was an asshole and they did not deserve it, and wish them the best. But after thinking about it for awhile, I became quite nervous what these people would really think about it.

I'm not doing this to save our friendship and I am not making excuses for the way I acted, I just want to finally take responsibility for my immature actions when I was younger. So does this sound like a good idea? Or should I just leave it since they have probably moved on?
<bot>: Want to know if it is a good idea to apologize over Facebook for ruining past friendships, or just leave it and move on.
