Snowwheel and others Im sorry you're feeling like this, it's miserable and you have my sympathy.
its been my experience in life that life goes in phases, and that things can change, sometimes dramatically. Over my lifetime I've had times when I've felt very lonely, other times not at all and then other phases in between. I understand that when you're on your own it feels harder to put yourself out there and go to places on your own.
I have a friend who is retired who for years had a bit of a fallow period in terms of having things of interest and social interaction. Then they found something they enjoyed - in their case being a film extra - that gave them an interest and that they were in demand for. It has been wonderful to see how that friend has blossomed - a sparkle in their eye, a keenness to interact and have a joke with others. It's wonderful.
There's something like that out there somewhere for each of you . It may well come to you, but it's more likely to work out and happen sooner if you can get out and about and talk to other people. If you want to win the lottery you kind of have to buy a ticket, you know? A chance remark can sometimes lead to all sorts of opportunities and discoveries.
Perhaps this quiet time could be a time to really think about what you enjoy and what gives you a sense of satisfaction and pleasure. Rediscover some old pleasures and interests and think of some new Ines you'd like to pursue. Who knows where the next twelve months may take you?
I wish you well in your endeavours. 💐
