Honestly?

Stay with what the doctor gave you. It can take a few months for things to adjust, and you haven't been on it long enough. This is the sort of thing that leads to you messing around with your own meds.

Give things time. Does the flat feeling suck? Yes, yes it does.

But you haven't lost yourself. You haven't been stable enough, for long enough, to really know who you are I think. Wait this out, let your body adjust, and eventually get to see who you are when you aren't bouncing around through episodes.

It might take the T and pdoc longer than you wish to decide to change dosages around if you continue being flat. Because they will wait things out. Trust them. Listen to them. Yes, advocate for yourself with them, through discussion. They don't know what you are like stable either. If things continue to be flat and numb, then the pdoc will adjust things.
