Is chastity worth pursuing?

For a 19-year-old, I've managed to seriously get myself messed up ually, to the point where I seriously doubt that I'll be able to sustain a healthy marriage. While this deeply saddens me, I don't want to hurt anyone, and when I look at the alternative, lifelong chastity, for all of the flak it has gotten it doesn't sound that bad. What do you think?
