08-18 with small breaks is not unhealthy, if you have made sure that it doesn't slowly turn into 08 to 00 hours.
You have been working for years and you deserve a vacation. But first answer what is making you chase the money. If you already have 3 years of expenses/outgoing backup (without inflation) - you are worrying too much. It might last 2 years with expenses, any inflation and leisure trips. If you do not have 6 months of backup, evaluate your financial situation, set a target date for a vacation and take a break anyways.
Second, why do you think you could be potentially replaced by competition? Is it that easy to replace you? It may not be as easy as you think. Try hiring for at least 80% of your capacity and you will know. If it is easier to replace you then the better option is to become a company/agency, hire people and expand your agency's capacity.
Third, if you take all projects that come your way - either your rates are too cheap and you need to increase - or you are exceptionally talented. In the latter case, demand for you will not die if you take a short vacation and/or defer some work. Don't plan for a long vacation like month or two, because it turns out to be boring and less fulfilling beyond 10-14 days.
With family, you might want to try out vacations at nonseasonal times if that works with the family.
When you do not take a vacation - you and your family will end up frustrated with any amount of money you bring in via that work. You might end up hating work at some point and will end up with some stupid decision.
