Hey what your feeling is completely natural.. When I was 18 I had already been addicted to exstacy. heroin. and cocain. I had a group of friends I had been hanging out with for years, since middle school we had been finding our kicks, and highs and lows with eachother. I then started taking more mushrooms than normal (normal was once every few months), and started taking doses of mushrooms and acid weekly. Quickly I found myself pulling away from these friends, started thinking about meeting new people, and leaving these ones behind. I have got random calls for years, or messages on facebook, of old friends looking to get back in touch. They always get mad and start bitching at me when i tell them "I dont care if your clean these days, I cant see you man, you were a part of my life, when my life was bad, and it is not healthy to be reminded of that daily...
There is a song, by a scottish singer/songwriter, called Caledonia. The first time I heard it, it made a positive change in my life, the second verse goes as follows.
I have moved, and i kept on movin,
proved the points that i needed provin,
LOST THE FRIENDS THAT I NEEDED LOSIN
FOUND OTHERS ON THE WAY!
I have kissed the ladies and left them crying
stolen dreams yes theres no denyin,
I have travelled hard sometimes with conscious flying
somewhere in the wind---
Look man, I went to arizona 2 years ago, I spent a summer all over the state, I found nothing but good people, people that were willing to come and talk, invite you over for dinner. I spent a month in the navajo nation, and I can tell you right now, a lot of those guys know all about tripping. But, having a friend is not about someone you can do a drug with, its something els, its like loves ally, a good friend. Just because your alone now doesnt mean you will be alone for ever. My advice for meeting people? go to festivals, concerts, and take the psychedelics you want, and meet great people who are interested in the same things you are, and better yet, are taking or have interest in taking the same things you want.. The options are endless, and using introversion or past hurt as an excuse, or to stop you from meeting new people shouldnt justify being alone. If your a good person, you need to get out and meet other good people, dont worry if your scared or something? if you start talking to someone about something, 99% of the time the person will respond and talk back, without any bad vibes or acting weird.. the only time I dont lean over and comment about something to the person next to me in in an elevator when you should just shut up and look at the numbers.. many people including myself have taken psychedelics and now find themselves looking for new friends, I think mainly because our perception has been widened, and we have seen things that others havent.. but the good news, is that there are millions of people out there taking psychedelics and thinking the same way you are, and trying to find good friends. all you have to do is lend a few words, and get somewhere to talk to new people. they are everywhere (possible friends), its just about putting out the effort, they will never just come to you and fall in your lap, the more energy you put into anything, the more energy you get back.
good luck man, best wishes for you.
much peace and love.
