Nope, it's official. This game is impossible, it sucks, and I want to nuke the Treyarch headquarters then hunt down and kill the families of those responsible for spawning it.
In short: FUCK THIS GAME!
Look, you said you borrowed this game from a friend to get your feet wet with CoD. Black Ops is my first console CoD game, and, coming from a very heavy CS 1.6 and CS:S background of PC FPS, it was pretty difficult to make the transition to sticks, but I stuck with it and I'm holding my own. Everyone is giving you the same advice so you should listen up and realize that it's your negative attitude and assumption that everyone is doing something different than you that is the problem.
Knowing your way around is crucial in any game, not just FPS. If you get lost, then hold up for a second, get your bearings, and move on. You need to slow it down and think. You're not going to get any better looking for a fight. Remember this is only the latest in a slew of CoD games, and many of the people you are facing have been playing for a long time (even some of the shittier ones). Expect that you ARE going to die, so make the most of your time spent alive. Don't waste it making decisions that make you more likely to get shot.
And as to the debate whether you learn more by playing and studying others versus tips and tricks, I believe there is clearly a middle ground. A lot of things are common sense: use cover, don't stay in one spot too long, burst rather than spray, and yes, you can learn a lot about tactics from watching kill cams, too. But, also keep in mind that people learn in different ways. There's nothing wrong with trying to find out more in depth information that you might not have noticed yourself, or get suggestions for loadouts that might be easier to new comers.

Change your attitude. Slow it down. Relish the kills where you've outsmarted your opponent. Relax and try to have some fun instead of looking for what's wrong.
