Exhausted and tired

I am a entertainer or exotic dancer. I'm 22 weeks pregnant and customers are starting to notice and ask... I feel so uncomfortable about it. I make good money. My husband and I are thinking it's about that time that I stop and be a stay at home mom and just work at the call center! He always works full time we have 3 other kids. All of us are high maintenance. I'm just so tired every day and every night. At times I feel like I'm losing my mind with exhaustion. When I'm not working I am at home with our 3 year old and I don't sleep in I feel bad making her stay in bed so I tough it up and get up watch cartoons make breakfast get her dolled up.! I need a day off soon!
