I have a friend who makes me feel inadequate but not by saying anything - just by being!
She's accomplished - she's a doctor, house with mortgage paid off (as I understand it), holidays on a regular basis etc, runs, plays netball, involved in many things.
She's pretty - tall, slim, good dress sense
She's lovely! Kind, friendly, easy going.
She's a great mum. Her kids are very, very well behaved, certainly whenever I've been around her.
She's wanted - she's begged by others to do things - run swimming lessons, first name on any get-together list etc.
Me? I'm larger than I'd like to be, too loud, crap hair, crap clothes, ASD child so appears badly behaved (he's not really, but people just see the meltdowns, and tbh, he is a little shit at times too), crap job, house is fine but needs work, no money etc etc. You get the picture.
She's absolutely lovely, and I've no doubt she has her own issues that I will never know about, but boy do I ever feel crap about myself when we see her. Mind you, it's not hard for me to feel bad about myself, I'm not worth much.
