I've tried, but there are multiple reasons.

First, I have literally less than zero money. I've been in education almost all my life because people always told me that after [insert degree] you will have infinite options and a good job. Well that doesn't really work if you're grades are always shit and you need 9 years for a 6 year degree. Its almost impossible to sell yourself during job hunting if almost every class has a barely passing grade. I also have zero to none work experience. In my country minimum wage is not enough to support yourself, and I don't qualify for unemployment checks. I've tried to find a job with my dogshit engineering bachelor's for 6 months, 100+ applications, nothing. Starting an apprenticeship pays even less than minimum wave. I'm already falling behind on my masters degree, while hustling on the side. I barely manage living paycheck to paycheck. All this while stuck living in my parents house.

Second, I got nowhere to go. I'm an immigrant, there are no relatives I could go to, all my friends have their own families so I can't couch surf, renting is to expensive. I would be fine with being homeless, but I got adult responsibilities now, that require residence.

Third, I've once been away for a few months, my dad almost cheated on my mom during this time but that's beside the point. That's probably the loneliest I've ever been in my life (granted it was peak Covid). There were times I haven't left my dorm for days. I had to apologize to people for my voice cracks, because I've literally haven't spoken a word out loud in days. I do not naturally seek out engagement, neither do people particularly miss my presence. I don't want to leave because the speck of social life I have is tethered to my family or friends in my city. Sure I get along with strangers fairly well, but it's all a facade, it's learned behavior that I picked up through the years so I don't get punched in the head for looking at somebody the wrong way (I apparently have a very 'punchable' face). I'm very carefull who I call a 'friend', and even then, the reason my friends are my actual friends is because we don't talk about topics like this.

My way of living has really thought me to give others the benefit of the doubt, because nobody can ever tell at a glance what going on in a persons life. If somebody is being a dick to me I try not to be a dick back, because I don't know whats going on behind the curtain. If somebody seems happy, I'm always asking 'Are they really?'. This way I've never had a road rage incident, I've never got screamed at twice. I'm really good at disarming conflicts, which is an almost useless skill in day to day life.
