I think it is normal sometimes to get fixated about ratings, winning, improvement etc. and this may lead to two harmful side-effects:
a) Getting anxious and feeling the pressure to use all free time for chess training. You may also feel guilty if stop working or try to 'create' more free time by avoiding other social etc. activities, and
b) Reduced pleasure in playing the game since you may be afraid of making blunders, lose rating points etc.

imo there is nothing wrong in taking as many breaks from chess as you feel like - you may even improve after a 'healthy' break. Moreover, I don't think there is anything wrong in prolonging a training schedule (e.g. a few years have already passed since I decided to make some serious study of the White side of the Open Sicilian - tbh I have never really started!) if you decide there are other priorities in chess or life.

All in all, if it is not funny I simply don't see the point. From time to time, you certainly need a break from your career, family etc., but you are not obliged to always use chess for that..
