Depression Stress Tired

This is my 4th pregnancy after 6years. Everything has back to square one. In this 32weeks i find myself cranky all over at home. My elder kids always get a scolding from me because of uncompleted homework. When i told the hubby, he just brushed it off and say, they just being children. But i get so emotional very fast. Im so tired and torn! Morning sending the kids, Afternoon fetching the kids. Prepare lunch. Then dinner. Intimate moment with my own partner is just out of the story already. Sometimes i just left the kids screaming and crying while me bursting with tears in the bathroom and lock the door.. ignoring them.. until then the hubby came back and the eldest let the hubby knows.. and scolded me big time.. what the most saddest thing, "ure such a burden making the kids worry!" Sorry for the long post.. is there any counsellor i can talk to?
