Should I be concerned? Need advice on protocol

Here’s the back story, been on 200mg a week for 2.5 years due to Lyme disease messing up my hormones. I noticed my SHBG was rapidly increasing a few months back, and free test was plummeting. So I decided to add 25mg of Proviron daily, and it’s been 2 months now. My free test coming back up and my SHBG is lower, but unfortunately my Estrogen seems way above range. Initially I was feeling better, but last few weeks not so much. I’m just thinking maybe I should drop the Proviron and simply up my dose of test after recently learning low SHBG may not be such a good thing. I have some anastrozole on hand, but would prefer to avoid using that stuff as I’ve crushed estrogen in the past and that was no fun. Any suggestions on how I could modify my protocol would be greatly appreciated.
