Do you think this is a good thing? I've personally tried to do the complete opposite, and I think it's thoroughly improved my life and mental wellbeing.
I think it's very possible to be introspective and aware of oneself while still seeing the good in everyone.
I hope you feel better :) Life has it's ups and downs, and I've found that time fixes most of it - we just have to learn to enjoy the ride (which can be nigh impossible at times, don't get me wrong)
