I am glad you had those great experiences.

Just because you are home doesn't mean they have to end. You call this apartment and feelings of loneliness your "reality". Well, some of it comes down to choices. Will you choose to stay home alone, or will you make an effort to get out more? What if you could join a community group that you're interested in, or even just keep in touch with your family? Even going out for walks alone would be very beneficial, just to get out of the house.

I hope you'll keep us updated on how you're doing.
