I strongly advise you study university in real-life and don't do online study.
Online study is very isolating socially and better suited for middle-aged people who already work a job and need to study on the side without having to spend massive amounts of money commuting.
A young person who likely only has a part-time job is far better suited to real-life study.
The social opportunities at university are also very important as there'll never be a time you're a young adult and surrounded by so many people your age ever again (high school is different as you're teens, not adults.
If you're already doing this, good stuff.
As for me?
*Sigh* due to me constantly moving, friends constantly moving, and such, I have no nearby friends and am completely and totally socially isolated.
I'm not sure what I want to study.
Working a job is too hard and I'm on disability payment.
I do volunteer sometimes, as many hours as I can do a week, but haven't done this in a long time and due to injuring my wrist I can't do it anyway.
I also can't lift weights or really do most forms of exercise for a few months now and exercise is one of the few things that makes me happy anymore in this miserably lonely, depressive life.
At least I'm over-time aquiring money from being on disability and using it to attain more items and things over time.
I am also an electronic musician and my personal home studio and equipment is almost full set-up.
