Yep, some doctors are better than others. It would be a good idea to calmly let the doctor know how you feel and let them know you are considering switching. It'll help them be a better doctor and they might be able to turn it around and really help you.

I've also battled depression from an early age, for me it was like 8. And when you have it for that long it becomes you, but you can always change. We all change more than we realize. Best of luck and much love to you
