I agree you should seek mental health professional, there is no reason you should have to suffer with depression, if there is something a pdoc can do for you, and there are many different meds that can help, I prefer to advise people with any mental health issues to see a pdoc vs a gp, they can better regulate your meds, that is their specialty, I did much better with obtaining treatment and proper meds than I did from my family doctors, my personal feeling and may not apply to others, is you need to see the doc for the right ailment/condition, you wouldn't go to a dentist for a heart condition right?
BTW Have you spoke at all with a talk therapist? They can refer you to a pdoc if you so need to see one.

Good luck, I know what depression is about, I lived it most of my life, sought help and have kept things pretty much together, not perfectly but much better than trying to do it alone.

Please take care,
