Sleepy in first trimester.

Abbiey
Im always tired. Im n my first trimester with my second baby. And a single mother to a 2 year oldd. Right now i am having to stay with my stepmother. Apparently she does not believe i have the right to b tired. I have no whr else to go right now. I have low iron and my two year keeps me going. But if i close my eyes for even 5 to 10 minutes i get told i shoulda thought abt tht whn i got pregnant. Is this fair ?
