Yes and no. I miss not having to try very hard on the work, but for a lot of high school I was pretty depressed (and let's not forget that I was a dribbling moron until I was about 16). To be honest, the happiest time of my life was between the start of 2012 to September, when I left for university- despite having a load of exams, life was great. I finally had a great group of friends, I had a lot of free time and I was vaguely on top of all my work.
It's not like I was one of the popular kids, it's just that my friends and I basically had minimum involvement with everyone else there, so they never really bothered us.
What I miss is being a kid basically, having your parents basically look after and not having too much to worry about leaves you without that many cares. Don't get me wrong, I would consider myself a massive failure if I hadn't gotten into university, and if I was living with my parents when I was 21 I would as well, but I do kinda miss it.
Right now, I have a deadline due tomorrow that no one on my course was made aware of until yesterday, I am in the middle of an argument via facebook with my ex-girlfriend, I am 180 miles away from my closest friends, I am dreading the prospect that we will probably end up drifting apart, the milk in the fridge has gone off, there's a small blue patch on the bread and I'm not sure I'll be able to afford to feed myself until the next student loan payment comes through.
Shit's pretty stressful, and I don't even have to work. Adulthood could fucking suck.
