Hi, and welcome!
From what you're saying, it sounds like you've had a very confusing childhood with your parents forcing you to conform to certain expectations. On first reading your post it sounds like they forcibly raised you as a boy - but is that
really the case? It's possible... but it's also possible that they simply let you be you, and when you showed a natural preference for boys' clothes and toys (like one of my daughters did), they simply respected your wishes. Have you asked them this?
I'm willing to bet that if you sat down and actually talked to your parents, you'll be surprised with what they have to say. I don't know you and I'm probably going out on a bit of a limb here... but I wouldn't be surprised if they told you that you were always a 'tomboy' from a very early age and showed a marked preference for the sorts of things that are usually associated with boys. I know this from experience, because one of my daughters was like that (and the other one was a sparkly, pink, girly-girl) so I've seen it happen first-hand. I also showed a marked preference for boyish things and behaved like a boy from the age of 18 months... which is pretty much as early as you can start being an autonomous human being.
Most trans people show signs of being trans from a surprisingly early age. I daresay you can't remember how you used to behave around that age - so is it possible that you were showing early signs of refusing to dress or behave in a stereotypically 'girly' manner, and that your parents just went along with it, hoping you'd outgrow it in time? I wish mine had, but that's another story.
So there's a good chance that you've always behaved in a boyish fashion & rejected girly things, and that your folks thought you were just going through a 'tomboy phase'. Most tomboys grow out of this around the time of puberty and start acting and dressing in a more feminine manner. If you're at that stage now, that would explain why your parents are suddenly 'freaking out': they expected that you would have started being girly by now and they're worried that you're not doing what they'd hoped you'd do. They're trying to encourage you to outgrow your tomboy phase... and it's worrying them that this seems to be something other than a simple phase.
I'd urge you to at least ask your parents why they dressed you as a boy when you were younger. Ask them how this all started. Was it their idea, or yours? I'm willing to bet it was yours. And if they confirm this, it's entirely possible that you're trans and were showing early signs, which your parents respected but perhaps misinterpreted as a 'tomboy phase'. In which case, you might want to do more research on what it means to be trans and what you can do about it (we're here to help!) before exploring your options.
Just... don't rush things on the surgery front. It's absolutely not true that many people regret surgery (over 90% of trans people are much happier after surgery than before) so 'trans regret' is a massive lie made up to discredit us. And seriously, I know thousands of trans guys who've had top surgery and I've never met one who regrets it! But
any surgery is expensive, invasive, dangerous and painful... so it should only be done after a lot of serious consideration. If you truly are trans, the first step is to see a gender therapist to help you sort out your feelings and what you need to do about them. Surgery, if it's needed, happens
way down the road. Transition is a marathon, not a sprint. As is convincing your parents, I'm afraid.
