Leo, many times I had to confront the health professionals I was dealing with, including the GP. It's difficult at the time, especially when you're not exactly feeling your best, but it's best in the long run. I THINK I have a better understanding with my GP....although that can change.
Clara, I agree with the others, sometimes AD's can stop working and I always think it's best to change them every few years. I don't think increasing the meds is going backwards. Think of depression like any other illness or medical condition that needs medicated. For instance, Diabetes and high blood pressure regularly have their meds adjusted. There's absolutely nothing wrong with increasing your meds for a while.
Sometimes it's difficult to make decisions when depressed. This is a vicious circle considering your decision is surrounding AD meds. If you previously responded well to a higher dose, then why not try it again? You just need to be more assertive with the GP.
I wish you well with this. Not nice at this time of years
