Frustration.. Wanna cry all the time

Cecilia
This is my third pregnancy. I have a beautiful daughter who is 5 and i had a miscarriage last july. Now in this pregnancy if feels like im facing a lot. I got married last August and he brought 4 kids into the relationship. I know its alot! So total we have 5 and the baby will be 6. I feel alone,frustrated, and aggravated a lot of the time. Now that its summer time i have all the kids everyday and even my nephews on occasion. Im stressed and my husband works at night so from 2pm til 4am im home alone with kids. I don't want him to think that i don't want the kids here because i love the kids but i also need a break. At least two days to myself with quiet and peace. What do you think i should do?
