Not sure

So, I feel like I'm on the verge of a breakdown...I can't get enough rest...I can't seem to manage my time, my kids, my house, my husband, my friends, etc....Not sure what to do or how to fix this....My husband doesn't seem to understand...He tells me all the time how good I have it and I do, BUT he gets 4 days off work in a row and I get a couple hours at a time if I'm lucky... Don't get me wrong, I love my husband and my kids, I just need a break sometimes and he doesn't understand...I'm so tired: physically, mentally, spiritually...
