Should I take an interruption
This is a highly opinion-based question, and difficult to answer. A more suitable question might be, "what are the negative effects of interrupting and how bad are they?". My short answer: you will delay your PhD when compared to a healthy version of yourself not interrupting, but not necessarily compared to your current self continuing. So, the first thing to assess is "will it actually go quicker if I stay, or will I burn out?". The second thing to consider is how bad taking longer on a PhD is. Short answer: not that bad, many students take long, sometimes many years longer. These students still end up with post-PhD work.

Concerns over other PhD students should be cast aside, you are comparing apples to oranges. The other students are presumably psychologically healthy, they do not need a break, whereas you might need a break. The taboo surrounding psychological and similar problems means we, somewhat irrationally, treat the issues differently from other health concerns. But you should address this in the same way as any other serious health issue.
