Same as above, your academic institution will have guidance counsellors and psychologists available. Believe me, you aren't the only student in this boat.

I admit, I am one of those individuals who went to university for no other purpose than to get away from home (my case dysfunctional and emotionally abusive). I was 17 and saw at the time no other option. I was there for all the wrong reasons and consequently wasted a lot of time and squandered a lot of money.

What would I have done differently? I would have taken a few years to do some self discovery and try to figure out what I wanted. I have thought about two directions I ought to have instead taken. I honestly think that getting a trade would have been the thing to have done. So too, I regret having not made strides early on to explore making art.
