Feeling Unsupported

Hi, I've literally just joined for some confidential advice.
My husband and I are expecting our second child in January 2018. This whole year has been a lot of ups and downs. I have had a few minor medical issues which along with everything else has caused me to feel fatigued, lethargic and sooo tired. On top of this my mother has just been diagnosed with cancer. I just feel like it's all getting too much and my husband isn't really stepping up to support me as I need it. I just want hugs and more help and a little bit of time to myself. I keep telling him what I need but he just carries on as normal. I'm exhausted and feeling overwhelmed. Any advice? What do I do?
