DEPRESION

I am totally depressed (as usual). This market depresses me. This process depressed me. I have no confidence of my ability in managing the process. How can you achieve your target without any confidence? But how could I not be depressed when as soon as I sold, the stocks started to move up, dramatically (again!)? How could I not be depressed when the market is moving up (as anticipated), but my stuff actually is going down? Isn't it sufficient proof that I should give up the whole thing? What did I do wrong? Just as the portfoli starts to improve and my confidence starts to recover, a few mistakes crush me, and my confidence. I really hate this thing now and I wish it simiply go away.
