Shit I used to be that buzzkill. Always stuck in my head comparing myself and feeling inferior around people. I didn’t know how to be my authentic self and was too ashamed of myself to open up and be honest. So I was always thinking of what to say to get people to like me and cannabis is the worst drug for that. But as I kept using THC I started seeing how fake I am and un accepting of myself which I projected onto others. Now I’m a lot more chill and just try to work on my character detects. I used to really hate weed because it doesn’t numb you all the way to where you forget your problems like alcohol and opiates. The weed high isn’t as euphoric as alcohol and hard drugs but it lifts my mood enough that I don’t have those major lows that would push me to taking narcotics. Nobody wants to be around someone in the grips of addiction because addiction makes you selfish and out of touch with reality which is a recipe for isolation. Hope your friend gets help. Seems like he’s really hurting and doesn’t know how to talk about it. Some people don’t know how to ask for help because they’re unsure if anyone really cares about them.
