Not saying they're all miserable but some do. I have a single female friend past 40 who acts miserable all the time and I wonder if its because she's single.

She says she fine with it but all she does is complain about work/life being difficult and its super toxic. To the point where its like whats wrong with you? Are you ever not unhappy?

I can totally see why no man would want to be with her. I wonder if its because nobody wants to fuck her and she's bitter about it. Maybe she's just unhappy in general.
