I'm two things; not a genius, and glad I'm not one

The smarter I become the worse/harder/sadder life gets.

• I get more depressed.
• People expect more from me when I don't have more to give.
• It becomes harder to form and/or keep relationships.
• Thinking more often begins to reveal the sad but true fact to you that the world is an awful place.
• People are annoyed by me more often.
• I overthink things too much leading to anxiety.
• I'm right too often (I know, it sounds stupid), so it's harder to be surprised. Being proven wrong is more pleasant than it used to be because I get more out of it.

I think it goes hand in hand with blissful ignorance.

^{(I feel the need to clarify that I'm not suicidal or hurting myself})
