Hi Stacy,
Hang in there! Your other posts are certainly worth considering, especially being evaluated by a professional.
Mental disorders can be difficult for even professionals to accurately tag. I do believe that there is always an underlying physical cause that leads to it though. That would be considered the root cause, and is likely biochemical. Having said this science has not evolved to the point of identifing the root causes yet, at best they are still playing with neurotransmitters. Meds are a God send to many people, and potentially dangerous to others. If you start on meds research the side-effects yourself to be familiar with them, Docs are a little to relaxed in educating their patients.
There are two Clinics that do some interesting research and treatment with regards to biochemical anomalies of patients. To their credits they buck traditional medicine even though they are highly trained Medical Doctors and have given many a patient their lives back. If you are interested in pursuing that path email and I'll give you the information.
I do believe in God, the Bible, and Jesus Christ. Therefore I also believe there is an enemy (devil). I have no idea where you stand on this but my other suggestion is to find a born again (somebody who has prayed and asked Jesus into their life, not just some one who believes in Jesus) Paster to pray with and for you. Prayer can be both protective and healing, find a strong Prayer warrior to help you - trust your heart!
Good luck, and God bless!
