It depends on the time frame & the people I am around and on certain successes or failures in the time frame mentioned. That said I'm happy if I'm given a reason to be happy & motivated & sad whenever I come across information or events that disrupts my good mood. Usually when I'm happy, I'm pleased with myself & when I'm not happy I do get sentiments of self rejection. That said I would describe it as a love/hate kind of thing usually influenced by life changing events. I think this kind of thing applies to most of us if not all of us.
