I am sorry you are going through this. It is so hard when our loved ones just don't seem to understand and believe it is all about faith. I am Catholic and believe in the power of prayer. HOWEVER, I also believe that we have medications for a reason. If you had severe asthma and required medication to breath would she insist on you just using prayer rather than medication? How about cancer? Would she insist on no medications but you could see a cancer doctor but only Drs with her religious faith and no medications?? What if the absolute best doctor for your situation were not religious at all. Would she turn away the doctor who gave you the best possible option of survival because of different beliefs? Mental health IS a medical situation that is treated the same way is other medical conditions. Left untreated or even mistreated depression is life altering and can be fatal.
