A lot of people said depression, but instead I want to focus on something else.

For your new job, you talked about how the work is similar, but how do you feel about your new job? Do you have a similar friend network of coworkers? How is your boss compared to your last one? Is the company culture the same or different. I ask because there are a lot of intangibles to a job that may not seem obvious, and the new job may not be as tuned for you as the last one.

Regarding fatigue and lack of desire currently, did you feel these feelings when you were unemployed? Were you working on a limited amount of energy before going to work? Were there cases where you would feel this loss of energy while out of work and looking for a job?

You are focusing on being unemployed, but the issue may be the new job.
