“Today I'm feeling overwhelmed. It's Sunday, what do you all do to keep yourselves busy? My partner is playing on his PC, my daughters are each in their rooms. I have PC games, my crafts, my book waiting for me... but I just can't manage to relax. Am I not normal? I feel so lonely surrounded by my family.”

Someone answered with kindness...
You're normal. Somedays are sometimes like that.
You could try and go for a walk. Quite literally, touch some grass, even if cold from autumn air. Knock on one of your daughters' doors, and explicitly ask if you can be there with them for a bit, that you're feeling a bit down, if they are old enough, and that you just need a bit of company.
And you keep it at that, just peaceful company.
