Looking for a nice group to play with

I've been having a few depressing games in team builder (trying to practice different champs and roles) and they've been dragging me down overall. Usually I can take losses constructively, but this tilt I'm on is getting rough playing with strangers each and every time. Hoping that there's a group out there that has room for someone just trying to play League with having other players flame or rage at me for not playing perfectly.
