You can generally either start with a doctor or a therapist. If you find a doc who'll start treatment under informed consent (i.e. you're an adult and recognize what you're doing) than you can forego therapy altogether, unless you feel you need/want it. If you're stuck doing a SOC transition, it'll be therapist first, doctor second, though that order can be reversed if a doc or therapist has someone in the other profession they work with often.
In other words, hold tight for 24 hours. Let me do some asking around and I'll talk you through your options once I find out what exactly they are.
