IL is very trans friendly. I don’t live there anymore but when I did I had my meds, doctors visits, and both surgery’s completely covered by my insurance. I just needed a few letters written by my team saying I’d benefit mental health wise from the surgery and I understood the possible risks involved. I couldn’t be fired from my job, and my coworkers would get in trouble if they harassed me.
If you don’t already the first step is to get a diagnosis of gender dysphoria or no one will take you seriously and you won’t get much of anything covered or prescribed. My doctor is super nice but wouldn’t work with me until my therapist gave him the diagnosis.
Never go to the south particularly Arkansa. They can refuse to treat you for any medical condition if your trans.
Your best bet is the west coast or North East coast and a few Midwestern states.
