Sophia Brooks, wow, going to the emergency room was the right decision. I'm glad you are getting expert help.
Waiting for procedures can be tedious and frustrating, but I hope the biopsy gives you and your medical team the information needed for a clear path forward.
Perhaps you do this already, but I found keeping a simple log or diary text document on my phone of events, medications, plans, advice, and schedules is very helpful. It doesn't take long, for all of those things to blur together, and loosing track is very easy without something to refer back to.
Gather information, make a plan, execute the plan. Repeat.
Sound familiar?
My experience has been that telling the tale helps with moving forward. Let us know how it goes.
