A few years ago when we were in our early to mid twenties I had a little group of very close friends. We met in 6th form and did loads of stuff together, going on holiday etc. Neither of us had serious boyfriends at this point so we were all big parts of each other's lives.
I'm ashamed to say that we fell out a couple of years ago (I'm 27 now so I guess I was ?24? then) when I had some personal issues and took it out on them a bit. I probably wasn't very pleasant to be around and things reached a head when I drifted out of contact with one of them and then we arranged to meet up. I had a "serious chat" with her and told her they had all been awful friends, but particularly her 

At the time I was so convinced I was right but now I can see it was me and want to make things up with them. What can/should I say?? Do you think they'll want to hear from me? Please help xxx
