I’m sick of being bad at this game SO MUCH!!!

I don’t play online anymore because my reputation and track record with quickplay or battle arenas are complete SHIT. 2 stocked, 3 stocked, it’s nothing but LOSING AND LOSING AND LOSING!!! I get it I’m bad at the fucking game

Edit: I’m a lot more calm now and for those who are wanting to give advice instead of laughing and calling me names or something? Thank you and I greatly appreciate it.
