I can relate to a lot of what you are going through. I think of what Dr. Viktor Frankl wrote about in his book Mankind's Search for Meaning. Frankl goes into the idea of people suffering from an existential vacuum in their lives. Frankl theorizes that humans don't ache for happiness, but rather desire meaning.
The writings of philosopher Alan Watts and the teachings of Buddhism are got me out of the dark, black hole I was in. Buddhism is nothing more than the first psychological analysis of the human experience and a means to end suffering. It is not a religion with commandments, gods, devils, heaven or hell. It is a liberation of the mind.
Life is just about experiencing existence. The brain traps us in resenting the past or worrying about the future. The only time we live is in the now. Live in the now. Try to make the world or someone's life a little better each day.
The more we accept what people label as "bad" the greater the experience of what those same people label as "good". Instead society has us chasing after pleasure and running away from pain. It's like watching patients in a mental hospital trying to fly by lifting at their shoes laces or escape their shadows.
