At first you should find out, what is the most important to you... Sounds like you have so much going on in your life right now, that it should be the first priority to reduce the workload / improve the work/life balance. I personally think, that university should be the most important part to put time in here, because it should be the most fun in the present and most rewarding in the long term. But the general rules and practises of staying focused still apply to your situation. Take a look at "Deep Work" principles and maybe as a fast and encouraging start, you can take a look at the analog principle of having a non digital notebook, a pencil and lists for "TodoToday" "TodoLater" and "TodoSometime" :-)
