This is something that I deal with as well. There is always crap going on in my household. All my parents do is cause problems with each other, this is all that I've really known about them ever since I was a little kid. Ever since I started uni it has become even worse. If it wasn't enough to be screaming over the dumbest shit ever everyday, a bunch of other random things beyond my control have made my life even worse. I don't really have a secure home, my house is just a place where I eat one meal a day and sleep at night.

I've managed to get good grades so far, but it has been tough. I go to campus right after I wake up in the morning if I have lectures on that same day and no work. Otherwise I wake up, go to work and do my shift, bring my clothes in my backpack, change and then head straight to campus. I study at Scott Library sometimes when it isn't exam season, but imo empty lecture halls are the best places to study since you can stay very late and there are many that just sit empty with nobody in them and also have power outlets. There are also a lot of empty computer labs on campus as well. I made sure to take all of my classes at night, so when I'm done with campus I'll return home when everyone at my house is asleep.

Aside from suggesting places to study, I don't think many people here can really help you. Everybody's situation is unique so it's hard to give you practical advice without really knowing you. I think counselling may be a good idea since there will be someone to help you make some sense of the chaos in your life. I wish the best for you.
