How do I create a group??

I really want to start a positivity group or something. Something that’s just to like spread positive vibes because like there’s just a lot of fucked up shit on here. I understand people need to vent, but being someone with depression and dealing with my own stuff, I can only take so much and just would love to be able to start something for those of us who maybe need a little laugh or smile or just anything remotely and genuinely good. But idk how?? Please help!! Thanks❤️❤️❤️

Edit: Thanks guys!! The group is called good vibes only, just FYI!! Feel free to join and post!!💕💕💕
