help please! so overwhelmed

Okay so in fairly young. 24 years old. Last semester of my masters degree program. My baby is 5 months old. Im so blessed and thankful that my mom stays with her the two days that i go to lectures. BUT i am also terrified. Back in june, i left my baby with her so i can go register for classes and my mom suffered a ruptured brain aneurysm. Miracles do happen because my mom didnt suffer any impairments at all. Shes normal and loves watching my baby. Im just always scared ill get a txt or a call again for a medical emergency. So im always anxious outside of my home. Ive asked her a million times if shes sure? I can look for child care and she refuses to leg me find someone.
