For a while, my emotions completely went away, but they've come back, and I'm afraid they'll be going away again. I sorta need help.
Fight nihilism; don't think, feel. You have emotions for a reason. What reason do you have to subdue them?
what is the problem, what is ticking you off?
Sounds like derealization/depersonalization? See a psychologist, they wil help you to figure out what is triggering this problem.
Why did they go away in the first place?
And what made them come back?
