I lost all faith and hope in the human race.
Meerkat,
Thats NOT the spirit... I do not advise turning your back on humanity. This is the humanity which Hashem has created. This is the humanity which the Torah so obviously demonstrates has foibles and failings. Imagine the story of Creation, the first man and woman disappoint by disobeying the one command they have, their offspring Kayin kills his only brother Hevel, the generation of the flood which robbed and raped, the generation of the Tower which flagrantly violated Hashems will, etc., etc... Humanity was not created perfect. It is our job, as righteous Jews and righteous Gentiles, to bring to this world the G-dly image which we were imbued with.
Mankind has the potential for so much good. You should look around you and acknowledge the good which is in your life. Appreciation is a big part of a Jews prayers, praising and blessing G-d who gives us life. As long as there is breath in your lungs and your heart is pumping warm blood to your limbs you have the potential to turn the world around.
This is my feeling concerning your condition. May you feel better soon..
