Hi Dark Energy,
I know what you mean about FB and I do use it myself. My contacts on fb have shared positive and interesting things during this lockdown. I think, from my experience, many of my contacts post their experiences in life (no thrills attached) I use fb for holiday inspiration and checking in on old friends from uni days. I also buy things for a bargain!
i guess it depends on how you use it and your vision of things.
my two best friends are not on FB and they do not have children. I know deep down they wish they had a family too. They are two of the most loyal and genuine people I know.
life has not ended for you and each day you awake, you have the power to make your life better. Believe that.
