Emotional for no reason

All day I cry for no reason. I’m over it, I want to cry again because it’s not time for my husband to be home. I don’t know if it’s just being lonely during the day since my husband works 14hour days. I have my 1 year old and 8 year old to talk to but I think I need adult conversation. Also it doesn’t help that I’m not sleeping much, maybe 2-4 hours a night. I do suffer from depression. So I’m not sure if the hormones are messing with that too. Ugh any suggestions on how to get in a better mood?
