Aibu or should I be worried?

I am knackered all the time. Just tired. I think about going to bed a lot during the day...most days. If I had time for a nap every day I'd have one. I do have nights out with friends etc but to be honest would be just as happy with a book and my bed.
I'm a busy single mum in my 30s. Have been this way for a while. Thought it was kind of normal to be honest but now I'm wondering if it is. Am I letting life slip by wishing it was bedtime constantly? Am I depressed? ( I don't feel particularly sad). Hoping to get some perspective or some wise words from here.

Go to the doctors and get your thyroid (amongst other things) checked.

How much sleep are you getting?
I have come to accept that my body wants 10hrs a night. 10pm to 8am is ideal. Now obviously I can't get that through the week but even just knowing when I am under-rested helps. I felt like a lazy sod for years and still do feel guilty and less of a good person at times for needing that much sleep but most of the time I've accepted it and am much happier for that.
I discovered 10hrs was my optimum on holiday without tv or Internet and without an alarm.
