That sounds like a good idea to talk to the therapist.
Sorry you had a difficult call with your mum.
Maybe you could make a case that having your art stuff gives you some inner peace because you are focussed on something and it does rest your mind in a different way if that makes sense?
Call me think but a kindle is a thing you read books on - yes
I have loads of books I haven't read but find it too hard to concentrate. If I do read a bit I forget what I've read......
Keep safe and keep going Lou.
