Honestly...it's totally normal. School adds stress. If you are working at the same time, that also adds more stress. If you live on your own and have to pay bills..that's also stress.
When I went back to college for my admin diploma, I was working two part-time jobs(working 6-7days a week), attending school full time(4hours a day, 5days a week..for 8months straight) and I was living with two of my friends so I had rent and food and all of that to pay for. I also, like most young people, did a lot of socializing(4nights+ a week). I usually worked, then went to school, then worked, then socialized at least 5-6days a week...my levels were often all over the place...though mine tended to be lower(though rarely below 8) in the morning, high at night*due to late night snacking and booze).
When you add stuff like school or jobs that aren't set times like 930-530 mon-fri..it adds a lot of stress to your body because you're getting weird amounts of sleep, you have deadlines that cause stress and it also fucks with your eating(mine still is haha) because you aren't always able to eat at the same time every day.
It's normal, and the best you can do is try and fix it as you go day by day. If you're high in the morning, maybe you need more insulin before bed. I would talk to you endo about possibly uping your evening dose.
