How is everyone in their careers? Especially the moms

Iv been trying to apply to some vocational programs but they are taking so long that now I’m looking into maybe taking out a loan to become a medical assistant because I’m tired of there little jobs like McDonald’s and target. Iim also nervous about how it will affect my credit score but I want to set myself up for my kids because I have no one helping me and a lot jobs give me issues behind my restricted schedule and end up paying for baby sitters which is hard. I really don’t know what to do.
