This was how I started out my journey too: by feeling dysphoric about being treated like a girl, when I knew I was a guy deep down inside. I went back and forth for a while, contemplating my feelings. I tried to force myself to become feminine (and I was a complete fake the whole time I was acting like a girl), I tried being just a butch lesbian, tried all sorts of different female identities, but none of them quite felt 'right'.
I'm now 19 years old and have been on testosteone for 6 weeks. I'm saving up for surgery too.
Feel free to PM me if you want anyone who truly understands to talk to. Also, I would recommend one of two things:
1. getting in touch with the trans community on YouTube - there are plently of videos on there by people like us, who talk about all these kinds of issues
2. taking a look at this website:

The more info you have about a subject, the better equipped you are to deal with it.
Take care, buddy.
