Well my situation probably gonna be a lot worse. Since here civilians aren't allowed to have guns, if something like this really happen, we have to use makeshift weapons. I've looked around the house and saw the things that can be used for defenses.
Tools such as wrench and hammers might work. I might use a plank and hammer the tip with nail spikes. I'd bring along a small one handed axe, a machete, some aerosol sprays, a lighter, bottles of kerosene and maybe few petroleums. A bike helmet for head protection, some really thick jackets(better chance of evading those scratches and bites), and a scarf to protect the neck.
Finally I'd grab my chainsaw and fill it with full gas. Then I'd head to the nearest bank or jewelery shop to try and look for any shotguns left by the guards(hopefully there'll be one).
