I see, just wanted to add after the last post, since it sounded like full DIY may probably too risky from your description: The physical changes will be visible at some point and things might end up badly once they put one and one together.
So if anything, that’d only leave puberty blockers: They’re more expensive than just injections, but they’d stop any further T-related changes from occurring and it’d take many years before anyone would notice that something is “off” and by that time you’d already have had legal agency for a while. (Naturally, you’d have to procure them illegally since you don’t have parenteral consent.)
(If you wish for physical changes toward a more feminine appearance getting your T down as soon as possible is unfortunatly pretty important for a good long-term result at your age.)
Saying something unpopular here: I don’t think that picture looks like “a cis woman” tbh. The hormones have definitely worked (if you aren’t convinced I’d recommend comparing to a decent sized pre-HRT shot and really zoom in and compare details on facial features one at a time including things like preceived facial diameter, it’s many details but they add up!) and you almost definitely don’t want to drop the HRT unless your trying to physically detransition!
However, if we met on the street I’d immediately guess “trans-women” and looking at the picture I believe the reason for this unfortunately is facial bone structure, particularily the upper facial half: the forehead is rather steep and the brow ridge is on the more pronounced side as well. (Maybe also chin, but not a big deal really.) Unfortunately, this cannot be changed with surgery.
As others have pointed out this may not actually be the source of your problems, but if your disatisfied with your physical appearance, I think this may be the way to get remedy.
