Pain??

I am totally pained with several issues.
I can't even sit down and point out what are the exact issues that are paining me.
I have lost the ability to think sensibly and am acting on my instincts, and most often, they turn out to be stupid.
I lose track of what I'm doing and start wondering if there is a point to what I am doing at all.
I do some things that are really stupid and avoidable, and then have to deal with the painful outcomes of it.
I get so frustrated with life that even things that should make me happy fail to do so these days.
I feel like I am going through the worst phase of my life.
I think I should go to a psychiatrist and get myself examined.
I don't see anything around me making any sense at all.
I am no longer able to explain my actions clearly to anyone.
I don't know what I should do next.
I should stop writing and get some rest.
