Hi, Sanzio, and welcome to Psych Central! I think you will need to ask yourself what you are looking for in a job. Was it the actual work itself or the long hours that was the problem or both? So, have you decided you never want another electronics technician's job again?
Are you looking for other work? Remember that you will need to hang on for a while with some job to get the experience companies are looking for.

But maybe that wasn't the job for you.
