Hello everyone, how do you know if you need a psychiatrist or a psychologist? I'm really tired and have been  depressed for 6 years but never seeked professional help.. I want to take the step but i'm also wondering how will the first appointment go? 
Ps. I am medically ill and am currently on many medications and treatments 
I suffer from autoimmune diseases, irritable bowel syndrome, brain tumor, asthma and many more other conditions 
I just really need help and do not know how to ask for it..
Tia
