Try somehow to figure out or negotiate a more comfortable situation in your current job (more remote working? non paid leave couple of weeks? educational leave? standing workspace? better chair?). Watch out for advises to change the job - ending up in professional void in this state, it might be very difficult to recover and go back into job market. One thing - time with the closest family (partner, children, parents) is never wasted.
