I just want to share this nice prayer I used after praying for other people's prayer request. A friend shared it to me after telling her that I feel tired after praying for someone.
"Heavenly Father, in the Name of Jesus Christ our Lord and Saviour,
by the power of the Holy Spirit,
we pray that the cleansing power of the precious blood of your Son come upon us right now.
Purify us and wash us clean with the blood of Jesus
from the top of our head down to the very soles of our feet.
Let this blood penetrate the very marrow of our bones
to cleanse us from any entanglement
from whatever spirit we have come in contact with during the course of our intercession.
Anoint us with the gifts of the Holy Spirit and refresh our body, soul, and spirit.
And may the sign of your Holy Cross drive away all evil spirits from us.
In the Name of the Father and of the Son and of the Holy Spirit.
