I understand, I used to have lots of intrusive thoughts. They actually started when I was 6 years old. Not long after I asked Jesus into my heart. I don't know if they were from the Devil, or just the fact that I have a learning disability, which means there is something a little off in my brain.
Dear Heavenly Father,
I ask that you will be with Gemmy. I ask that you will help him or her to get over whatever intrusive thoughts that are bothering them. In Jesus Name. Amen!
