Am I doing things right?

Hi guys, I’m 23 single mom of a 15 month old. Once I had my daughter I moved back with my dad, got a car and drivers license and am currently in my first year of college. Everything is relatively good compared to when I first had my daughter (and was struggling terribly), but somehow I still feel kind of empty. The days are long but also somehow too short, I never have time for myself but when I put my daughter to bed I feel ashamed as if I didn’t pay enough attention to her. I’m constantly worrying if my education is going to be a waste of time in this political climate. At night I try and compensate for the lack of “me time” by up staying up way too late and end up feeling drained the next day. I just feel like on all ends I have no peace.
Is there something wrong with me? Do I lack appreciation and awareness? How do you cope with all these feelings of anxiety and inadequacy? How do you manage personal care? How to stop worrying about my financial future when I’m not financially stable?
