Hello Iambluetoo and welcome to the forum. It can be frustrating trying to get help. I don't know why the doc said what she did, but I do know the following.
Depression does not care what sort of job that we have or how well off we are and it can strike anyone. It is listed as a major illness by WHO (World Health Organization). One of the key items that depression does to us is that it causes a negative outlook towards the world. By that I mean, I might not find my job in the least stressing, but if depression comes along then all of a sudden I may be unable to face work the next day(actually happened to me, I had a job I loved and suddenly I couldn't go to work anymore).
Depression may also make a lousy job worse and cause anxieties to worsen. Anxieties can also cause depression to worsen so I can understand you being upset.
I wouldn't give up on trying to get more help from your doc, but you may want to take the "Check up from the neck up" quiz provided by the MDAO
https://mooddisorders.ca/program/check-up-from-the-neck-up It was developed by the MDAO and Sunnybrook Health Sciences Centre, Department of Psychiatry (Dr. Anthony Levitt, Psychiatrist-in-Chief) The Ontario Psychological Association The Ontario College of Family Physicians, Collaborative Mental Health Care Network and you can print this part off as well.

Sometimes docs listen a little better when you give them answers that speak their language (I know that's not fair, but that's how it is sometimes). Taking the quiz and printed everything out may allow you to persuade your doc that you have a very real illness.
In the meantime please do not hesitate to ask questions, answer other people's questions and/or use the forum to vent out a few of life's frustrations. Take Care. paul m
