@50minusONE, I’m sorry to hear you’re struggling with depression. I’ve definitely been there.
Unfortunately there are few quick or easy fixes. Also with winter approaching the shorter days are especially difficult for those with seasonal depression.
Best advice I can offer is activity.
Find an exercise you enjoy, try walking or jogging outside to get fresh air and daylight (also get as much natural light inside your home as possible), perhaps your JCC offers something of interest?
Get something on your calendar to look forward to like a meet up with friends, a weekly class, plan a visit to a museum, or take a trip to a new city to explore.
Volunteering especially with children or pets can be very gratifying and is a great way to feel needed and loved.
Find a new hobby, gardening can be therapeutic and you can start small with 1 indoor plant.
Reach out to others for support, the CR is a good start.
