hi for christ
a really good thing that you should do is realize that you are dead in Christ and that is twofold
you, like all, are dead in sin
trespasses and sins, for the wages of sin is death and all have sinned
which you most probably know
and them go forward in faith to who you are in Christ
for Christ
and as Paul wrote and that so by the Holy Ghost
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. Galatians 2:20
O death, where is thy sting? O grave, where is thy victory? 1Corinthians 15:55
I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction: repentance shall be hid from mine eyes. Hosea 13:14
and now
for christ
for Christ you live and you are His
purchased
For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. 1Corinthians 6:20
so if you have to tell the devil where to get off do it with this truth
that you have been dead and now are His
fully for Christ as His
and rejoice in this over and above everything else including how your body feels
it is possible and you CAN do it because the Lord delights in your praises
and one more thing that often helps shake us is to remember that we shouldn't tell our God how big our problems are but tell our problems how BIG our God is!
