i feel like an alien too but without the drug part (maybe the internet). Not hooked on anything yet still unable to pursue meaningful relationships outside the preexisting few I have left. Lately I stopped expressing ideas to people, since most of them are just rejected or get swallowed up by the void. All i'm trying to say is that there *might* be something more to the social part.
You gotta keep trying. Also could be you’re in the midst of a social circle that isn’t empathetic or just doesn’t click. I had to move and explore until I found people I connected with
