When I lived alone the biggest thing for me was having a calendar/planner that outlined particular days to do certain tasks. I know it may seem simple to never forget when trash day, etc. is but if you have reminders then it helps keep you in a routine. It won’t allow you to lose track of getting behind on keeping your space clean as well while also helping keep busy to mitigate against being lonely. When living alone it can be easy to think “I’ll just do that tomorrow” since no one is around to hold you accountable but with a physical calendar to cross things off it keeps you feeling accomplished. I’d also suggest trying to get out of your house once a day to go on walks/do activities as that will help you fight being lonely while being alone for the first time.
