I work in mental health and one of the psychiatrists I worked closely with had a chat with me about it one day. He agreed that from what I told him and from what he had observed in my day to day work, I more than likely had characteristics of it - along with my anxiety.
It seems to feel worse to me since having DD but that is probably a mixture of being a bit sleep deprived and my anxiety about being a mum etc.

I struggle to finish projects, bore easily and flit from idea to idea, amongst other things.
