First of all DAMN you had to be really pist off to do that. Once i broke a wall that hadended up with a hole 3ft. high and a door in a fight with a F*CKER that harrassed my GF. any ways hmmm... Let me think i think home depot can help you out there. Just call your nearest home depot and ask them what to do. They have helped me do allot of crap like fixing a kitchen sink and to build an extra room to my parents house. Which is the room where i build my models. to bad im moving out.
Hopefully that can help you out in your hole problem that you have.
