Let me be the first to help you out instead of ******* you......A bad catalytic converter can cause a few problems. It usually depends on which one it is. Looks like you have a 2005. You can either have 2 or 4 catalytic converters based on build date.
If you only have two, it could be sending false signals to the front 02 sensors causing your engine to dump more fuel into the motor.
If you have four catalytic converters and its one of the back ones, it will just cause a CEL to come on and throw some trouble codes. This shouldn't affect your truck except to have that annoying CEL light on.
Goto your local auto parts store if you don't have a CEL reader and get them to print out your trouble codes. Then post them up here and some of us can be a little more helpful.

I believe it is only 100K miles not lifetime. The converter uses two different types of catalysts, a reduction catalyst and an oxidation catalyst. Both types consist of a ceramic structure coated with a metal catalyst, usually platinum, rhodium and/or palladium. The idea is to create a structure that exposes the maximum surface area of catalyst to the exhaust stream, while also minimizing the amount of catalyst required (they are very expensive).
It is highly unlikely that your 2005 is already bad, if it is go straight to your dealer for a free replacement.
