It's hard to avoid letting your wedding take over your whole life, especially on the extra-stressful final stretch. But your hobbies, friends, and interests are what keeps the anxiety wolf from the door, so letting those slide is a bad idea.
It's hard to find the time, but by delegating tasks and decisions, giving yourself a long enough engagement and cutting down on some of the unnecessary detail you may well find you still have time to be a person too.
I ditched a bunch of hobbies to try to claw back some additional planning time. It was a bad idea, as I started to lose all sense of perspective. I didn't feel like myself, which in turn meant it was hard for me to be a happy, breezy bride (which was never going to happen anyway, but a girl can dream).
The only thing I didn't drop was my daily dog walk, mainly because that would have been a bit unfair on the dog. Thanks to her, I at least got a daily dose of exercise which helped centre me. Whatever your favourite activity is – yoga, meditation, shots, or arguing with strangers on the internet – don't take the risk of dropping it.
