[Mindfulness.]

Hello there,
I'm sorry to hear what you're going through.
As Dez mentioned, if it is safe to do so, I would talk to your grandmother and mum about the situation in regards to your underwear and how it made you feel as she shouldn't be taking photos of your clothes like that.
Do you know of any local jobs that are hiring to get you through until you find something that you like?
Good luck with the job hunt and talking to your family if you decide to.
