Hey Retail Worker How R UUUU

Hello to all the people out there who work retail. Hello twice to people who also have children. Let me start off with a Siiiiiigh. Okay. So I've researched this online and have not really come up with any great advice. 1st of all let me say that I know that there has to be some solution and I may just be looking over it. So I work in a job where I work on commission and hourly and my hours vary. Some days I have to be at work at 8 am and get off at 6, sometimes I have to be at work at 1130 and get off at 830 pm or 9. My biggest complaint is that I cannot have a SET schedule everyday as far as what time to eat breakfast, lunch, exercise, shower, go to bed... All together my life just seems chaotic because of my hours (and probably some other things). I am seeking advice as to how I could have a set schedule, short of having a new job. The reason having a child is important is because it seems like the only way I could have a daily routine (which is what I deeply desire) is to have go right before work to the gym (but then I have to shower at the gym, which is what I don't like because 1. I don't want to haul all of the stuff everyday and 2. because I would have to drop my daughter earlier and give up time with her. I work 40 hours a week and go to school 7 hours a week. She begs and cries for me to not go to work as it is. lets face it, I might get 1 or 2 hours in the morning with her and mayyyybe 1-3 hours with her at night.) or I could go to the gym or exercise right after work, but again the time changes make it so that the only day I get off early enough to spend significant time with my daughter after work is going to be taken up by going to the gym. I know some of this is excuse, but its also a real life problem and I'm sure MANY people deal with it. I'm just looking for working parents or working mothers, maybe full time like me, who work retail and deal with the same problem and/or the guilt. I think the guilt comes because I always felt like I didn't get enough time with my mother and didn't have a father and/or because my closest friends are stay at home moms (not that its easy to stay home).

IF anyone has advice on how to have a more organized life and work retail so that I could have a more routine day-to-day life I would greatly appreciate it. So far the best plan I've heard is getting up really early to get things around the house done and exercise. Sometimes I don't get home from work until 9:30 or 10 depending on what time the last customers left, which just means I would need to come home and go to bed like immediately.
I am sorry about the run on sentence (S)

Add on: I never really had a big problem with losing weight or staying in shape when I was a waitress and had a set schedule, also because of the walking. It has been the biggest problem since I started working where I work now (7 years ago).
