Been there done that! 10years in company, we got downsized, got thrown away like a trash. Took months to deal with emotions and set myself to do anything. In the end I realized that I was relying on job to be an anchor in my life that everything was revolving around. Losing that anchor forced me to search for a new one, more reliable and something that I can control and that makes me better.
I started with cleaning my house, then deep cleaning shelves and such, then basement, etc. Got interested in working out, and started doing pushups and such. I learned that I was missing that - creating my own schedule, having goals of my own. It was scary at first, ngl.
Trying to do small steps, very small sometimes, that improves your situation bit by bit is what I found helps me with being overwhelmed.
Wish you all the best, I hope you recover soon and find better job soon :)
I did that when i got laid off in January. Can recommend. Mental reset helps. Having no job helps with refocusing on whats really important, like own mental wellbeing, family and friends. Good times, tho i got pretty stressed out because searching for new job took a while, despite everyone else in IT got one in 15mins it seemed at the moment
