Thank you for requesting my help with your question.
A person cannot become lazy just because they had a stressful job. Usually when someone has worked very hard for a long time, they can become burned out. Burn out can be a high level stress that comes from working beyond your normal capacity. As a result, you overcompensate for what you don't have to give the job and end up depleting your body and mind. Once the job is over, you experience the effects which can include:
You can experience these symptoms even if it has been two years. This would be particularly true if the stress was over a long period of time and/or the job burnout was never fully addressed.
If you experience burn out, seeking help is important. See your doctor to be sure there are no consequences physically.
Take time to rest. You may need a long vacation or an extended time off working.
Seek out support from friends, family and co workers. They not only can help, but they can provide understanding that few others can.
If you find that you still feel burned out even after you have tried some remedies, you may need to talk to a counselor. What you are experiencing may be emotional and a therapist can help you find out the root of what is causing it.
