There are some people not doing so well since being laid off. Seriously not doing well. Please seek help.
Feeling anxious and depressed, having trouble sleeping, not being able to enjoy activities that you are used to enjoying are all normal feelings that you may experience after a layoff.
If these feeling persist over time it may be useful to be assessed by a doctor and/or mental health professional. Layoffs can put a lot of emotional stress on relationships and it may be useful to consult with a mental health professional about this as well.
