Getting to live alone, this suddenly, is quite the experience. It's not my first time, though, but I have quite a lot more responsibilty
The city I'm living in is quite expesnive, and my monthly revenue is very small (under the SMIC; the minimum wage in France); budgeting is of upmost importance. Thankfully, ressources exists; in my case, there is a service for that, helping people with various disabilities. For the youth under 25, there's also the "Mission Locale", but they're underbudget (ty Lecornu /s), and not always very specialized into neurodivergent folks.
My living space is relatively cheap, at least by my town's standards. Hovewever, the thermal isolation is shit. It's getting up to 32°C (close to 100°F) during the day, and it's april.
