You'll have lots of time to make new friends, friends who are on the same wavelength, bring out the best in you and inspire you to achieve more. I moved countries a couple times and each time ended up with a new bunch of friends. I was always "cool" but cool changes over time and being a stoner (or worse) turns out not to be so cool at my age and I feel ashamed. Some of the friends from my teenage years went down the harder road and are in drug rehab, jail, or dead. I'm now thanking my younger self for running away from that lifestyle. Easier said than done I know. I have to give up some friends myself and I'm struggling but just today I saw someone who I avoided befriending before (because they are not a chronic stoner) and I arranged a time to hang out with them and play sports. Life is long, people come and go.
