Hey Kevin-
I'm 22 also, and after four years of heavy drug use, I finally sought couseling and recovery, and oddly enough, those "little pricks of emmotion" inside were a huge topic of recovery. I think through growing up, especially early childhood, the majority of us, not everyone, are taught to "suck it up," "be okay." Even growing up in a pretty healthy enviornment, we learn a certain amount of denial because "our lives aren't that bad," look at those other kids. The abused. . . The homeless. . . The starving. . .Point being, we shouldn't feel bad. Which is true. Odds are, no matter what we grow up with, someone had it so much worse, and we shouldn't pity ourselves. But I think somewhere near this age, if you were taught to not feel sorry for yourself, somewhere in childhood, that transposed itself into "don't feel bad. Period." Those pricks, those moments of sadness or anger or hurt, those moments of surprising emotion, even for a second, are real. They're somehere inside of you, and they didn't just come from nowhere. The majority of people will go through life without ever facing those quick moments, quick feelings. And the fact is that life is busy, you're only going to get busier. But if you will trully take that journey inside yourself, open those doors that are clearly almost completely shut (why else would an emmotion inside of you come and go so quickly?) you'll be a better person for it. It's not quick, and it's not easy, but it's also not a thing that's going to completely throw your world upside-down. It's simply working on a different way of viewing the world, searching through your emmotions that are really there, even if you don't know for sure that they are, and through the process, dealing with life on a steadier foot.
Take Care, Try it out, and don't get freaked out when everything inside of you says no because you're sending a change to your emmotional and mental way of dealing with things-
