I'm going for ND and MH issues.
I only say this because what seems batshit to all else, can actually be a real anxiety issue.
Nearly 30 years ago my hairdresser would turn the chair so I didn't have to see my face in the mirror (I was actually lovely looking). I got a dream job 2 years ago, but would not put my face on screen for the training. Everybody else did, we all looked normal etc, but I just couldn't.
I haven't had my photo taken willingly in the last 15 years. My Mum started saying that the kids will look back and wonder why you were never there!
I wouldn't have my picture taken with my Nan, my everything, even though I knew she was dying.
So... It's not bullshit.
OP, what I would suggest is getting a photo of yourself, or one of you and DH or DD and using that as the picture and at least say hello to your family.
Of course they are going to think it's weird, they do already! Baby steps though and a little hello now and again, and new photo every couple of months if you are up to it?
I don't know what makes me, or other people this way, but it does happen.
All the best X
