I'm so sorry, Teawithsunshine. Losing a job sucks - I'll say a prayer for you. Heaven knows I've been there before a few years ago and so has my husband. Just remember that exercising may not always sound like fun but it's great for the endorphine boost to keep your spirits up. It really does help keep you motivated in other areas of your life.
When my husband lost his job, he actually used the extra time he had (besides looking for jobs) to train for a bike race which he's never done before. It really helped him stay optmistic and healthy - and he surprised himself with how well he did. Now he competes all the time.
So, like everyone else said, I would use this time to focus on your physical and mental health and lean on us for support
It's just a matter of time until you find a job and later you can look back and be really happy with what you accomplished and the new hobbies you've found durng this hard time.
