I’ve just started to read Liz Nugent’s first novel (having already loved her second and found her third quite compelling). This one is looking promising:

It turns out that I am a violent man after all. It comes as a shock to me. I have been psychologically assessed. I decided to tell them almost everything. Apparently, I have been harbouring bitterness, resentment and frustration since my childhood. Now there’s a surprise.
