Living alone sucks. The transition period after a long relationship ends also sucks. No amount of advice from anyone can fill that void for you. Having said that, you have to at least give yourself a chance to go out there and stay in the real-world as much as possible. Some ways to do that would be to just walk around your city/locality/town aimlessly every day before or after your remote work time since there is no reason for you to stay at home beyond that time - have a step count goal - don't go back home until you hit that goal, treat yourselves to local food, make small talk with random strangers, get back on dating apps - meet people for fun. Staying outdoors, moving at all times or as much as possible can do wonders. Also, since you work remote, consider moving to a different place to work. Good luck.
