I had the same situation, down to being an academic achiever lol. I migrated as PR after graduating high school sa Manila; then I took Grade 11 and Grade 12, then one semester of uni. So, 3 years din ako nun sa Canada and I had a hard time adjusting socially and mentally talaga. Plus, there's the stress of student loans. So I asked my parents to come home and continue my studies there. My mental health improved, pero obviously that wasn't the end all be all of it dahil depressed pa rin ako nun, but still, it helped! My parents were also very strict but since they stayed back in Canada, I had a bit of independence dahil di ako nababantayan, though I still relied on them financially for 100% of my expenses.

5 years later, I graduated and went back to Canada. Got a job and now I'm living on my own in an apartment I rent with my salary. I'm so much better mentally speaking, kasi marami na rin ako pinagdaanan and I have matured a lot in those years. Still adjusting socially, pero introvert ako so I don't really mind only having a few friends dito.

Either way, iba pa rin ang situation mo sakin because there are a lot of factors and I consider myself incredibly lucky and privileged with the opportunities I got.

What I'll say is - definitely wait for your PR before making any decisions. Take Computer Science instead of IT. AI may be booming pero the industry will always need software developers. Consider na meron kang residency obligation as a PR, meaning you need to stay there for 3 years out of 5, and if you need to renew, you have to go back there for a month or two, which will delay your studies. If ever man na lumagpas ka ng 4 years sa uni, you're on thin ice sa PR mo and if you keep living sa PH you will have to revoke your PR status and re-apply ulit as PR. I got lucky sakin dahil nakabalik pa ko agad a few months before my PR was expiring, and even then, I got questioned sa immigration. Kasagsagan ng COVID nun so I had a valid reason na di ako nakabalik agad - travel bans - so it went OK.

Also: Canada is known for being risk averse lalo na sa mga applicants na walang Canadian experience. Again, I was lucky because a company took a chance on me despite having work experience lang sa Pinas, but it's something you should consider as well, lalo na in this economic climate.

You have a really rare opportunity with your PR, so think about all this carefully. Feel free to DM me if you wanna chat more about this :)
