After having contributed to tens of projects, and managing a few, I had to take long breaks and even close down two of them - that can be painful. Helping out is great, it's awesome to see people happy about each new release, but the burnout is not a joke, and I'm glad you're taking a break to find the much required point of equilibrium.
Enjoy your break, as long as it needs to be, and thanks for all your hard work so far.
