I know exactly what you mean "friends" are very difficult to come by and most of mine go back to school or college days. I also have a large extended family that mostly live closeby although we get on well enough and respect all the family sensitivities, they are relatives not "friends".
Acquaintances, that's different, people you meet regularly at the activities you go to, you chat, have a coffee but there is no real connection, they have their existing lives and an outsider finds it difficult to become close. Cliques at clubs or even work are difficult to break into, as a newcomer you just have to start your own group with other newcomers, it needs a proactive approach and of course an open mind because others don't have the same likes and dislikes as you.
I do have one good friend that I made maybe 15 years ago we are quite different, we disagree on politics, she is hard right, I'm soft left and have quite animated discussions but a good friend she remains.
Tip, avoid groups of 3 there is always a gooseberry and it might be you!.
My sister is a good example of no friends, she married (badly) and moved to Australia had a 2 nasty divorces, she now lives with a guy and has a part time job with meals on wheels. She has no friends at all that I can see, no relatives, her children dont speak to her, it's just the people she works with. A miserable life.
