I'm so fucking done with nunu

What the actual fuck am I supposed to do to him? He just walks into my jungle and takes things with twice the true damage I have, heals off of that, is Tammy as fuck, and can even 1v1 me with his bullshit base damages. His e and r slows and attack speed slows are disgusting and without a teammate to help me fight him, I just lose everything. Even if I had 2 teammates help me with him he would still get my camps because his q is complete and utter bullshit. I'm so fucking done with that champion. Makes me actually want to fucking kill myself and quit the game forever.
