I am in a similar spot to you. At uni & live alone. It is hard doing it all alone and I commend you for juggling all these things so you can better your life. I don't have any answers for you, but reaching out to others as I did today, helps. Tomorrow I will start a thought diary again and try to incorporate more mindfulness into my day. I did a telephony consult with a counsellor at uni and she took me through a body scan/ muscle relaxation/ mindfulness exercise. I provided me with good relief of the strong anxiety I was feeling with looming deadlines and perfectionism.
I think also getting back to some basics has helped (but is still a work in progress). This includes getting my butt on my bike and getting exercise, good diet (soups), good night sleep (keep to a routine, no study after 11pm).
It's hard, I hope you and I both get there.
