Guatemala Update

Hello all!
thank you for taking the time to read this.

my preparation for the dental mission trip has been alot of prayer and handing things over to God in prayer when i start getting anxious. ive never been so anxious before, not that i can remember. i keep hearing random things about guatemala.
pray for my mind to be focused on the people i am going for, and the people i am going with.
please ask with me- for selflessness. i tend to want to make things all about me, and how is this going to impact me?
 pray for unity of the team, and obviously good communication. mostly coming from me. i tend to not communicate well.[ not for lack of trying.]
please ask that we would be able to go in full health. i have allergies, and theres no infection, thank God. but it really would be annoying to have to blow my nose while trying to do these other things.

Gods teaching me rest this year, more than other years, and i am having a difficult time currently trying to balance doing what needs to be done for the trip, and taking calming breaks.  also, i have a tendency to want to have all my EVERYTHING situated here before i go away on any trip. even when it doesnt need to be touched yet.
God mentioned fasting to me, as lined out in isaiah 58, and i have no idea what to do with that information. im scared to fast; i feel like its not safe for me to skip food. but hes telling me something here. so, that if im fasting, i would do it with wisdom and peace. and if it is for another reason, that i would hear that clearly. but i think hes telling me to fast.
thank you so much for your prayers
