Here's a saved post for a similar occasion; hope it has some relevance for you:
I really should have a stock saved answer to this question because I'm sort of tired rewriting the same thing all the time. In fact let me look. I wrote this last night in response to a PM:
"Well I know that story. (What would happen if you lost the most important things to you) What happened to me was that I was a wise guy. I wanted to know the truth. I believed in God and I wanted to prove He existed to everybody so they would try to be good. I wanted so so much for there to be happiness and beauty and everlasting life and a reward for good. So I set out to prove the good and I found out that there's nothing, no truth, no answer, no reward, nothing but the cold benign indifference of the universe. My live went black, empty, hopeless. I could barely breath. I was a walking mass of pain. Came across Zen. Not a tile above or a place to put your foot. But they were smiling. WTF WTF's with the smile. In the middle of the night pondering over this, the wind hit the house, mind stopped, and my heart, my heart, my forgotten heart came back to me.
You know the Zen story, the one about the guy chased over a cliff by a tiger. He's hanging on for dear life (to his opinions ) and below there's another tiger. Muscles tiring he sees a strawberry growing on the cliff. He plucked it and it tasted so good.
For what I know, not much, I paid with every thing I valued. You are not your opinions, you are a chimpanzee full of piss and vinegar."
Well that's a brief version of my story. I KNEW that I would never be happy. I knew it with all my being, er, except for the part I hadn't been since I was small. A blast of wind turned me inside out. I have never suffered since and it's been a while. Now there was this instant change that revolutionizes your understanding, but you remain, in many ways the same. I am still unconscious of all my feelings and have had some opportunities to explore them. I can tell you that sadness, depression is suppressed rage, and rage is a defense against feeling hurt. We are up against a powerful opponent, the desire not to know, not to remember. I have seen people collapse into their feelings and I have done it. You cannot imagine the quantity of rage that is buried or the enormity of pain and hurt and grief that lies below. To tap into that, to know the fastness of suffering we experienced that for us today would make us laugh, did make me laugh is like bleeding lava out of a volcano. The relief is staggering. At our core we are joy. I met a man who had been down all the way. He was a sun.
Now there is another issue that must be carefully considered. I can't say for sure that all feelings of unhappiness are purely psychological in nature. You may have chemical depression and could greatly benefit, be enlightened by anti-depressant drugs. You should, in my opinion, at any rate get yourself evaluated by a professional. I thought of death many times in them days. I'm glad I didn't take that route. We have been made to feel bad and there isn't anything wrong with us at all. The one exception may be the chemical thing. Don't know if it's cause or effect, but that one may be easy to check and treat.
