Two years ago I moved out of London and now live about an hour or so away from most of my friends. A couple of my closest friends have only been to see me twice since I moved and make a fuss about how far away I live/how expensive the train fare to see me is etc. They don't seem to realise that it costs me the same amount of money and time to travel to see them (which I do fairly regularly and without complaining) as it does them to see me 
We had planned to meet up on Sunday for lunch (in London) which had been in the diary for a long time and I was really looking forward to it as I haven't made any friends in my new area (mainly as I work irregular hours and have a long commute) so I only get social interaction every few weeks and am pretty lonely.
One friend emailed me on Saturday saying "not going to be able to make Sunday lunch anymore, got a few other things to do this weekend". I forwarded this on to the other friend saying X can't make it but I'm still looking forward to lunch and she replied saying "yep hectic weekend for me too, had a crazy week, will have to pass on lunch too".
Neither of them bothered to say sorry to letting you down / sorry for cancelling at the last minute / let's try and rearrange or anything along those lines. Also their reasons for cancelling were a bit vague so makes me realise I am just not a priority.
This is not the first time things like this have happened, just the most recent example, so I am starting to think maybe it is time to move on and try and make some new friends, who live closer to me and value me more Sad as I have been friends with these people for years and have been through some difficult times with them by my side but I am just not getting the right vibes from them anymore and don't feel like I am a priority for them. Even when I call and leave voicemails I never get a call back, just a text a few days later.
Has anyone else re-evaluated old friendships and moved on?
Should I speak to these friends or just let the friendships run their course?
And how do I go about making new friends? I am finding it so hard to meet local people as I work ridiculous hours and don't have DC to meet people through. I do have some hobbies I have met a few people I chat to, but I find it hard to make the transition with people between being people who say hello and have a chat and friendship.
Feeling quite lonely so any advice much appreciated
