Invaders make me Quit

It's literally my first playthrough of Darksouls 3 and no 5 minutes after I ember I get invaded, whatever I do I just can't do shit. I'm playing as a pure pyromancer so I can't just throw my cast slots away for bs spells to just get by in PVP, I wanna play the game, jot get invaded, I also wanna play online and summon people. It's making me seriously consider quitting the game.
