If time is your only limiting factor (meaning you've got money and aren't relying on insurance for therapy), there are online therapists who could probably accommodate you fairly quickly. You may not get a referral for testosterone by the time you leave for school, but it may be faster than establishing care in your new location.
For the other concerns, you're going to have to get in touch with your university.
- Registrar: They can update your name in the student records. Call and ask if they have a place in the system for preferred names. Explain your situation.
- Health Services: Call and ask if they have mental health professionals on campus. Ask if they have any doctors/PAs that specialize in LGBTQ care. If the answer is yes, ask if they have experience administering transgender hormone replacement therapy. You may be able to get things taken care of at school.
- Residence Life: If you're planning to live on campus, you need to get in touch and ask for appropriate accommodations, otherwise you'll end up with a female roommate.
- All of your first semester professors/teaching assistants: Send them an email and let them know: what class you're in, what section you're in, what time/day it meets, your name on the roster and what you would like to be called.
