I am 32 weeks pregnant and have two weeks to go until I start my maternity leave. The thing is, I've had really bad anxiety this pregnancy and feel on the brink of exhaustion. I love my job but I also have two young children, one of whom has started waking up several times every night and is difficult to get back down. This morning, after another broken night's sleep, I had a panic attack trying to get us all ready to go out. I would love to begin my maternity leave next week so that I can focus on reducing my anxiety and catching up on some sleep but feel I'd be letting work down. Any thoughts?
