I couldn't have said it any better!
OTR, Make sure you find time to communicate with God every day, and more than one time a day. And when I say communicate, I mean talk to God. Tell Him how you feel and tell Him you want to be healed. Ask for guidance and healing. Pray, and get into God's word. Read the story of Asaph in Psalm 73. Find your sanctuary and make time to get into the Word. God's word is power.
With that said, I am by no means an advocate of faith healing. God has given doctors and other medical the gift of healing and the heart to serve others through medicine. My wife had surgery for breast cancer in October and she is now finishing up her radiation treatments. We prayed and asked God to guide us to the right surgeon and the prayers were answered. We're taught in ministry that the spiritual body and the biological body must both be treated.
In your case, I advise you to pray for God's guidance as you seek treatment. Ask Him to send you to the right doctor and that he'll be able to prescribe medication that will help without the harmful side effects.
My wife has dealt with this since 1996 and much more is known today about depression and how to treat it than ever before. There are better meds and they know more about the chemistry of the brain now than in years past. Looking back, I can see now that my mother suffered from depression for many years back in the 60s and 70s, but no one knew what it was or how to treat it. All they did then was prescribe Valium. I think my mom slept for about twenty years because the only thing doctors knew to do was to sedate their patients who complained of the symptoms of depression.
Put it in God's hands and take advantage of modern medicine. They can tailor a treatment plan for you that will help.
And again, get into God's word. If you don't have a Bible, I'll send you one at no cost to you.
One last queston: are you able to travel?
