Can I do this? (37 yrs old)

I’ve thought of being a mom for several years. I love kids and think it would be incredibly rewarding to raise a child. Maybe people have told me I’d be a good mom. I work as a high school math teacher so luckily I would have lots of vacation time to spend with my child.

When I think about the day-to-day of being a single mom, though, I’m really not sure how to make it happen. My parents are an hour away so they could help sometimes but not all the time. I have friends in town who would be happy to help babysit occasionally but again I don’t have anyone who would consistently help out. I think one of my biggest fears is not being able to deal with the sleep deprivation. In my life experiences so far I really don’t deal well with a lack of sleep. A few times in the past when I went to work with less than 6 hours of sleep I got a terrible migraine and ended up puking. I’m afraid of being incapacitated by sleep deprivation and being unable to take care of my baby on my own. Thoughts??
