I'm the same as you. It's took me years to realise my friends aren't going anywhere if I don't see/speak to them daily or weekly. I still don't get me wrong feel like you do at times especially when I need to talk to them. But I have had to learn to be patient. I'll send a message and wait if I haven't heard anything in a week then I text again. I use to cry after leaving my friends it sounds pathetic now. But I would cry for hours.
