How much good do you do for your current group if you aren't able to meet your own needs? (answer: not as much as you could do if you made sure to meet your own needs).
While giving back is a great idea, when time is limited, sacrifices must be made. Do you sacrifice yourself, or do you assume that the people in the group will continue to go on without you just as they did before you joined? (answer: they will continue on just as they did before you joined)
Take care of you first. The rest will fall into place.
