It sounds like you've got lots going on and are keeping busy. Busy is good as long as it's making you feel the way you want to feel at the end of the day. Even some levels of overwhelm are a good thing, as long as we can hone back in and always be aware of what exactly is consuming out time and energy.
I wish you success in theses big things you've got going on, self awareness is where it's at. :)
