I will pray for you! I do believe that God heals, and I also believe that He allows us to go through hardship and illness. Sometimes, we also need to seek the help of professionals i.e, doctors, therapy, maybe medicine. I am glad to hear that you are hanging onto your faith in spite of negative experiences in the church. Remember people (even servants in the church) are fallible and will hurt and dissapoint us, but He never will. He will never leave you or forsake you. You may be going through a trial, but there will be a growing experience from it. Do get some help from your doctor for your panic attacks if you haven't already. You can learn tools through therapy that can free you from this. I also recommend learning some relaxation and breathing techniques to help calm you-they really turned things around for me. If you enjoy music, I found a lot of strength in listening to worship music. Delirious? in particular is an awesome band-powerful lyrics.
Prayers, and hugs to you-let us know how you're doing,
"Courage is not the abscence of fear, it is feeling afraid and doing it anyway!"
