Honestly I would hide as long as I can until the military comes and rapes all but if theyre all dead I would shoot myself instead of trying to survive as I would rather a quick and painless death then to be eaten alive by 50 zombies while simeultaniuosly having my limbs brutaly ripped off.. If you seriously believe you would be able to live through a zombie apocolypse you need help.
Okay now, assuming Im forced to try and survive instead of hiding/suicide, I would definitely grab a sword as you dont need to reload like guns. I would prefer a long and thin one for a long reach and quick swings. Next I would get my dads friends AR15 because he let us borrow it to go shooting and its still at our house. It started raining a few days ago when we were shooting so we had to go home early which means I have a shitload more bullets. After getting a sword (probably a katana) and the AR15, I would run to the police station near where I live for protection. After safely getting there, I would realise I would never survive a fucking apocalypse as I said before and I would shoot myself before being eaten alive by 50 zombies while simeultaniously having my limbs brutaly ripped off.
