For many, having too much to do and too little time to do it in, is an everyday occurrence. Claudia Hammond is an academic psychologist and award-winning broadcaster. She hosts BBC Radio 4's All in the Mind podcast, where she offers practical and evidence-based tools to help us take on everything life throws at us. Her new book, Overwhelmed, deals with imposter syndrome, procrastination, fear of regret, perfectionism and a seemingly never-ending to-do list - and it offers a way out. Claudia speaks to Susie Ferguson about how to deal with that dreaded drowning feeling.
