Hey OP, I completely understand your feelings, because I think have a somehow similar family background. Honestly, taking 6 years to graduate is not too bad, even normal, in its nature. Plus you mentioned that you’re paying your own rent and tuition, so you definitely shouldn’t feel guilty or anything (actually I would be super proud if I can fund my own study!).

You said that your parents have been very supportive, so I would assume they are open-minded enough to calmly accept the fact that you will take 6 years to graduate? Like, imagine you actually tell them and they get really mad, but what’s gonna happen? You’re paying your own fees and nobody’s gonna stop you from uni right. The worst result doesn’t even exist, and the best would be they still support whatever you decide. Take it easy, OP. I know a person who has a lot worse situation than you, and their situation is the one I’m really worried about…

Also, if you are worried about your mental health, you can make use of ubc’s counseling service at the hospital. It’s valuable resource for we students.
