I don't know if you have seen my question yet I know you get a lot. I have another question. I know a psychiatric service dog will help me. But I don't think my doctor will agree because he always acts like I'm over reacting when I'm not I don't know what to do.
First, this sounds like you may need a different doctor. if your doctor is not listening to you they are not the best to have around just for your own sake.
The way I asked my doctor about it: I brought the ADA laws about service dogs, what the requirements were, and how I fit into those requirements. Then I talked through a list of tasks that a dog could do for me. When presented with the facts, my doctor was more willing to listen because she didn’t have to do her own research to see if she felt comfortable writing a letter for me.
