Am I mature enough to keep watching the show Breaking Bad?

I was just recently introduced to the show Breaking Bad. I live under a rock with no cable and don’t watch much TV but heard that this one was truly special. Well, I watched the Pilot and found myself hanging onto the couch the whole time! The show is so intense and just does not let up.
I am trying to limit myself to one show per night and am now at Season 2 Episode 2 (the one that ends with a bell ringing). I’m not sure I can take any more. Is it because I identify with the guy? The way he was doing the math in seven thirty seven, or his being a scientist, or having cancer really strikes a chord. Oh my! Does the show continue to get more intense? Is it going to get worse? I’m finding myself strangely worked up and exhausted after each episode. Regular TV like NCIS etc. just seems silly and bland in comparison.
While I really like the show and desperately want to know what happens next, if it continues with this intensity, I don’t think I’m mature enough to keep watching. It takes me too long to wind down.
I thought TV was supposed to be mindless drivel.
