If your weekends are spent for the purpose of recuperating just so that you can have the energy, strength, mental acuity, and sustained focus and attention to go back to work on Monday, then it is an indicator that you may need to file for Federal Disability Retirement benefits under FERS or CSRS; if, after each day of work, you are so profoundly fatigued that you end up spending each evening just resting, unable to have any significant recreational enjoyment or time for relaxation, time with family, etc., then it is an indicator that you may need to file for Federal Disability Retirement benefits under FERS or CSRS; if you must take sick leave, LWOP or annual leave every few days, or after a week of work, because you need the time off to recuperate, then that is a further indicator.  Ultimately, each individual must make his or her decision as to the timing and whether one has reached a critical point where filing for Federal Disability Retirement benefits under FERS or CSRS is necessary.  Different reasons for different people; different factors at different times of one's life.
