I I literally can't play my favorite character

What im suposed to do in this situation? Im main Dracula, also Ghost face and pig but I really enjoy playing dracula. This mmr basically don't want me to play my main. Every single match IS against p100 gangs so I can't get even 1 kill without playing too focused, wich I don't enjoy. I don't want to play like a sweaty person every game. Should I play friendly to decrease my mmr? And no, I can' just have fun, when I am using a new funny build I get destroyed and tbagged.
