I'm getting so upset! My daughter is 15 months, she typically sleeps through the night but last night she had a rough night. I've been up with her since 4 and I had an interview today for a job my fiancé's mom doesn't want me to get. Ever since this morning, his mom keeps reminding me she won't watch my daughter for me to work and that I absolutely can't work and go to school in the fall. That it is impossible. Anyway, I went upstairs to wake up my fiancé to take our daughter and he said he will later (which means when it's her bedtime so I won't get to rest) and when I came back down i said "I'm so tired" so his mom said "imagine working and going to school and having her. You can't do it. You can't even have her and do the interview without being exhausted" well bitch, maybe if your son helped some I could!! Tons of women, even single moms, work and go to school and take care of their kids!! It isn't impossible!!
