I've been struggling incredibly hard lately coming to terms with somebody not loving me back. Then I woke up today just not caring at all. I don't feel depressed, my body is showing no signs of stress, I was able to concentrate on my job ok. It's just... gone. If I think of her I kind of would prefer it if she was still into me but there's none of the pain. Is this something I should worry about? Yesterday I was a complete mess and literally couldn't get out of bed
