I can see why your doctor thinks you might be depressed. The whole not being able to concentrate and memory trouble. Plus the eating...are you eating because you are tired? Also, the carbs cause us to feel soothed.

What did the psychiatrists say? GPs are good, but they aren't specialists in psychiatric medicine. There may be better medications for you that will target your needs much better. A psychiatrist would know.

If you feel like you have more than you can cope with, getting a therapist to help you might be the way to go.

Also, having family move away is stressful and can put you off center.

Best wishes.
