After finding out I have TMJ.. and after my jaw keeps locking, 

I've decided I am going to pray against it because I feel like Satan is trying to SHUT me UP, and that is not gonna fly.
He tried to SHUT me UP in Africa whenever I was unable to breathe. Fear of being that sick. Fear of what would happen to me. Fear of praying in front of others. Fear opens the door for the enemy.(to have authority over me) Once I overcame those fears, Satan couldn't keep me(the Lord) from speaking. So now. He is trying to keep me quiet again through tmj, and being too scared to pray for healing.

The fear of man brings a snare, but whoever leans on, trusts in, and puts his confidence in the Lord is safe and set on high. Proverbs 29:25 (Amp)

and from my favorite verse that i quote all the time..
His word is a fire SHUT UP in my bones. Satan is trying his hardest. But I am on fire.  

And after going to the hospital a few weeks ago because my migraines were so unbearable.

I've decided I'm going to do something that is totally impossible, and it freaks me out.
I wake up and go to sleep with headaches/migraines. I'm pretty much used to them and can push through, but sometimes it just wears me out. It affects me and who i can/need to be.

I am going to pray AGAINST these for the WHOLE 11 MONTHS while i'm gone. From the smallest headache.. to the worst migraine. I do not want any of it, not even for a single day while I'm on the mission field. It will get in the way, affect my ministry, be distracting in prayer..etc. 
I do not want to take any headache meds either. Which is impossible again. I can barely go a few days without them now, much less 11 months. 

but God is a big God. And I believe this is a step of faith. He will be there to catch me. 
I don't want to do this. Bc my little mind cannot fathom a miracle this big and is telling me it will never happen. 
But how is God supposed to show Himself, His LOVE, and His  GLORY if i only pray the "answerable" prayers.

If the jaw problems and headaches do not go away, but remain in order to serve as a thorn in my side.. I will still give Him the glory, and humbly thank Him for His love through every migraine, and choose to trust Him through it all.

That is why I would remind you to stir up (rekindle the embers of, fan the flame of, and keep burning) the [gracious] gift of God, [the inner fire] that is in you by means of the laying on of my hands. For God did not give us a spirit of timidity (of cowardice, of craven and cringing and fawning fear), but [He has given us a spirit] of power and of love and of calm and well-balanced mind and discipline and self-control. Do not blush or be ashamed then, to testify to and for our Lord, nor of me, a prisoner for His sake, but [with me] take your share of the suffering [to which the preaching] of the Gospel [may expose you, and do it] in the power of God. [For it is He] Who delivered and saved us and called us with a calling in itself holy and leading to holiness. 2Tim.
