It's not lonliness, it's solitude. Time to find yourself and your creativity again.
You were codependant and need to learn how to be independant again. Living for you, just for yourself. You've spent most of your life living for others. Now it's time for you.
Try not to drink alcohol. Focus on your physical health. Gym/tennis/saunas/running/golf any physical activities you can.
Yes.
Boredom and solitude go hand in hand and enable growth and the possibility of freedom. Independence of thinking, integrity.
Hell, even modality that depend highly on thinking on your own.
I've got too damn busy life these days and am missing the solitude so much.
But in the beginning the thought of boredom and loneliness can be a monolith.
