That's encouraging! Volunteer work often pulls us out of ourelves and the depths of our misery to see results that we are helping someone else. It can absolutely be very healing.
I think they want the six months so you FEEL a comitment. I think you also have a lot of free wiggle room there. Talk to other volunteers. I'll bet they are in and out of there. Maybe even re-enlist. Good luck to you.
