Zerg & Terran vs Protoss & Protoss Help

My friend and I have just joined the 2v2 ladder and we seem to have run into a problem when facing the Protoss x2 teams. While I (the Terran player) build 2 barracks and pump out marauders as fast as I can, my teammate desperately tries to build enough roaches followed by as many hydralisks as possible. What ends up happening is that the Protoss players each build 2-3 gateways and rush us with enough zealots to overrun either my teammate or I. If we do survive the first wave, we are often overtaken by the next string of stalkers and such. I was just wondering any good strategies to stop this rush.

Thanks in advance

 

you(as the terran player) should wall off early. then, pump some marines... don't tech straight to marauders because they are weak against zealots.. your mate could get a few banelings too. they **** zealots... make sure you know what they are teching to tho...
