I’m afraid I’ve no idea of costs, I presume just the NHS prescription charge so £9 per med. Yea their website is not great but if you email them a person will get back to you and they’re super helpful and friendly. They’ve helped out a lot of trans people (and got a lot of stick from the Telegraph etc). I don’t even think you’ll need to travel, online appts and then pick up from your pharmacy. Best of luck!
You’ve been thinking it about it every day for months. You need to do it. Speaking as someone who started transistioning within a year of sobering up, you’ve been masking the pain of dysphoria with narcotics. That will kill you. And the dysphoria will get worse as you age. Do you talk to a therapist?
