>>12It's not a weird question or at least not for me. I think if you isolate yourself step by step, they will slowly get used to it - or they will ask you to stay because otherwise they will miss you.
If the first case: They are either understanding or they won't miss you that much. (Which is a bit sad but meh, we humans are selfish.)
If the second case: There is a chance you realize that you do need them and for receiving love you have to give love by listening to their problems. Being part of a group has it's downsides of course, you can be harmed in any second and as people get to know you, you are getting to be more and more vulnerable; but if you are always alone, you are strong for nothing.
I didn't really have high school friends as I was a kind of sick (eating disorders and whatnot). I spent most of my time observing and understanding people rather than like them - now I'm a university student and though I have friends, they often call me scary and they respect me more than love me. It's a kinda, I don't know, bad.
Long story short, value your friends while you have them.
