Don't know what to do ( advice / support ? ) (crossposted from r/transteens)

I've always wanted to do hrt , (for around 5-6 years at least). I have had dysphoria but I've just stopped looking / thinking about myself to the point that I "don't" and it's become sort of bearable these past few years.
The other day I started actually thinking about myself for the first time in a while and it hit hard, made me realise that I do very much still want hrt and the fastest the better. I have come out to my parents and we did have a talk about that where one of them said that it was fine as long as I didn't do any surgeries or T or "weird things like that", that was when I was around 14-15 so I'm not sure if they'd be fine with it now?
For now I've planned talking about it with them again when I'm 18 (around half a year from now) but I honestly don't know if I can , since it hit I've just kept thinking about it every day
