I'm so glad your doctor has listened, is getting more testing done, and has given you something to help get your brain chemicals back into balance! you are doing great and the medication should start really helping. One thing about taking medications for mental disorders - some people might be critical and say "just get over it," "Pull up your bootstraps," and other misinformed ****. My viewpoint is that someone with insulin dependent Diabetes cannot have balance by themselves, or just with diet - they NEED medication to help them. It's the same with mental disorders; therapy alone isn't helpful for many people - they NEED medication, too, in order to attain balance. I've been taking anti depressants for many years and I'll probably be taking them for the rest of my life. All a part in keeping the balance for me.
Just hang in there and know that better days are ahead. GO, girl!
