Self pity is the worst because you stop taking steps.
Taking steps is easy...
To seriously address your points
1. Don't study a degree you don't like. You learnt that the hard way, fine, is suspending your studies right now an option or are you forced to continue till the end of the first year? You've probably thought of the former and sssn that it's not an option, otherwise you have taken it.. which sucks.
2. From a students perspective it definitely seems gloomy and scary and a whole world of things but on my placement year I've seen and done jobs that are genuinely enjoyable.
3. You get skills and experiences, whether it's through your course but largely driven by what you get up to. Imagine putting down that you were the president of your SU... okay, that's an unrealistic goal for 99.9% of people but there are plenty of things inbetween. But I can relate to the opposite of this because admittedly I struggle socially just a tiny bit and lack interest or talent so this has been a limiter for me, and I guess this can be what makes uni the opposite of fun.
