I was a happier person before because I had a very positive view of others, but I had issues with the darker emotions. Something happened (a lot of negativity) to me and I actually feel more right brained, and more depressed, and suffering from existential angst. I know it's not healthy for your world view to revolve around others, to be dependent on them for my happiness, but I really feel like certain brain circuits, the desire to connect, to care, have been shut off, and I'm stuck in this depressed state.
