Hi wow90,
It’s so hard to be depressed and have no direction especially after being goal-oriented and optimistic for as long as you could remember!
What I would do is revel in Routines. Find pleasure in the small things.
Wake up. Make coffee. Go to your favorite breakfast take out place. Order a different thing from the menu each day.
You will be working soon. Yay! Something to look forward to and fill your time.
Explore your block. Every lunch/afternoon go into one new store on your block.
Talk to one person you see in your building every day. The doorman only counts once. Goal: Invite a neighbor over or go out to dinner/coffee with him/her/them.
Find a church/temple/Buddhist meditation place. Do that once a week.
At night find a Netflix series to watch. Only watch one program a night. Then read only one chapter from a great book a night. This will give you something to look forward to.
Good Luck!
Inky
