Running out of steam...

Things have been really busy at church...really busy...and stressful.  I am just the type of person that gets my feelings hurt too easily, and I make impulsive committments too easily...not a good combination.  I just feel like I've gotten in over my head with "church stuff".  It doesn't do any good to do all of the "church stuff" if you don't have time or energy to read the Bible and pray.  I have really been stuggling with this.  I am just not sure what to do about it.  I need to learn to say no...but is saying no to "church stuff" like saying no to God?  Is it?
