Exhausted and about to pull my hair out!!!!

Laura

My husband and I, along with his parents are caring for our neice (20 months) and nephews (3 and 5). Their mother left them in our care after finding her mother dead on the 13th. Their father (My husband's brother) is currently incarcerated. I don't mind helping, since she is going through a lot right now. However, I'm exhausted between taking care of our daughter and attending to their needs. It didn't help that we all got the stomach virus, except my husband. Our nephew and niece are not over it yet. Their mother is supposed to come get the two that are still sick and take them to the doctor. My husband was talking about gbetting temporary custody of the children. I'm not sure I want to do that. We are not in the best position to take care of 3 more kids. I want to finish school and my husband is gone a lot. All the childcare would be put on me.How should I handle this situation?
