I have also suffered with a fecal Body Odor for 12yrs, I have been a born again christian for 23yrs. When I dedicated more of my life to Jesus in the area of obediance it seemed that my Body Odor had increased. I too was embarrassed, ashamed and it made life hard, it made it hard to be a witness for Christ Jesus. Mainly when I tried to testify how good GOD is, when people would come around me, they would hold their noise, turn their heads, move away, change their seats, and so on. I am a minister of the Gospel, I have pastored and have been asst pastor. I have been quietly judged by other christians as not having a strong, mature relationship with GOD, because of my physical condition. I have cried out to GOD in Jesus Name, I have fasted many times for many days these past yrs, with no change. The Holy Spirit has revealed to me in prayer that #1 I have to trust Him, #2 Its a physical condition with spiritual attacks. #3 Look for the right medical help. Seek and you'll find, Ask and the answers will come, knock and the door will be open. I found your message because I am seeking, asking and knocking. Lastly I to have had that suicide spirit come to me, with its lying self trying to get me to quit trusting GOD. I know GOD loves us both and He has work for us to do, so keep fighting the good fight of faith.
We will make it together, GOD Bless you and your family.
