Develop a mental health history. It doesn't seem like you have one yet. You should see a psych doc. Once you start seeing a psych doc and taking meds, it goes in your health/insurance records and establishes a history. Unfortunately, they don't take your word or look at the fact that you have a pattern of unempployment or being fired (even if it was b/c of your mental health).
They look if it can be measured medicallly, length of time, the degree of illness. How it affects social functioning, daily activities, concentration. If you have been hospitalized or suicidal (not necessary).
