Depression And Over-Thinking

Firstly, thank you so much for this platform.
I find it super, super helpful because I don’t always feel brave or confident enough to communicate face to face on coaching sessions.

I have read elsewhere that depression and over-thinking are closely linked (I’m paraphrasing but that is how I interpreted it).
This obviously resonated with me since I find it fascinating thinking about my mind and what is going on in my head but often don’t like the realization when I hit upon something that is demonstrably true.

A perfect case in point would be the realization that ultimately the only reason anyone does anything is for the feeling that they themselves will feel. Again, this rings true to me but makes me feel incredibly guilty and narcissistic.

I don’t know how to NOT feel guilty or narcissistic without becoming a psychopath!
