While you try things, try to remember - that's what you're doing. Trying things. Some work, some aren't a "fit" for you. But if you keep at it, you'll find things that you like and that recharge you.
I get the missing the best friend bit. It is not what you asked for. I get the introvert thing. I'm not one, but I get it.
It may be that social things aren't your bag. So as you keep trying, maybe you need to find something that doesn't require extroversion, right?
Enjoy the weekend!
