Have you tried BP or anything else yet? It's working well for me, but I know it can be irritating. I just use a tiny bit in my moisturizer and that helps my skin not get irritated. Tazorac is supposed to be really good, but I've never tried it as retinoids are generally not my friends.
I really hope you find your happy place soon. Maybe going off the tane and trying something else is a good idea.
Let me know how it goes.
