I too suffer living at home with S18. He has his own life which is awesome but we connect minimally. Honestly that is how it should be in my opinion. He needs independence as he goes off to college next fall.
But, its many lonely evenings. I'm reading... texting friends... I'm fortunate and am an essential worker so I get face to face time with coworkers but they cannot be my social network - I'm a lot older then they are and I'm in more of a higher position. I adore them but do not socialize outside of work.
Life has changed dramatically. I hope with the lifting of stay at home I can figure out how to be my own person again and find my own things to do and make my life more interesting.
