sometimes i feel so depressed even in non ovulating dates, i feel worthless, sad and hate the world and my life and when i feel like this i dont want to talk to anyone or do anything, and my mom gets on my case that life its a struggle and we need to go on with our lives. nothing traggic has happened in my life, no reason to feel like this, and then in other days i feel like i could accomplish anything in the world and feel ok, but then i get anxious and depressed again, why do i feel like this?
