I inherited a lot when I was 18 after my Grandparents passed away in an accident when I was in high school, and now in my early 20s am pretty much set for life financially considering I live a minimalist lifestyle and got lucky with some investments.
I'm always depressed with anxiety, no talents, no passions, and have always compared myself subconsciously with people who are superior in every way. Basically the small % of people who are seemingly perfect in every way. I have nothing going for me to be happy about, and sometimes go weeks without being able to look at myself in the mirror or an kind of reflection.
I would trade every penny to be healthy mentally.
