YOU are the real you.
It can seem a tricky thing, but I'll start with the probably obvious thing. That being that with meds, the you being you is a matter of a good cocktail (or monotherapy if that's what works for someone). The goal of course being whatever keeps you you without getting problematically low or high (or at least for shorter timeframes).
You have tried a bunch, so another thing to consider is the relative newness of the dx and hypervigilance. While it's good to be vigilant, it's possible to be overly so. Sounds like that might be a significant factor in your confusion. Questioning and dissecting every little thing is crazymaking. It would seem worthwhile to dial that back a touch and see if that helps.
If it does (and I think it will!

), then you could work with boundaries
if that is a problem for you. They're separate things (ie. You being extroverted and boundaries. You could have boundary issues regardless of being extroverted or not.)
