It can take a while to get over a layoff when it’s unexpected, it isn’t so different than a relationship ending. We spend a lot of time at work and often put a lot of ourselves into our jobs.

This could be depression or just delayed grief as needing to find a job on short notice tends to block out a lot of emotion and it can take a bit after getting a job for that block to loosen.

What helps you get out of the funk and what helps someone else get out probably varies. For me a decent walk around the neighborhood/park and decreased phone time are/were very helpful. Even mild alcohol use was a very temporary thing that created a long-term detriment. Society sucks at teaching healthy coping mechanisms.
