I understand how you feel as I've had long hair pretty much all my life. I started experiencing hair loss last year a few months after having Covid. It almost stopped ( I did use minoxidil treatment) but now I am noticing that it's starting up again.
It is extremely emotionally distressing! I don't want to cut mine (it's below my rear end right now) but I've been wondering if it would help the loss.
Thank you for sharing and have a lovely day!
