Virtual, you have a lot in common with a lot of the people here. Playing video games as a different gender is actually a very common sign of being transgender, as is wishing you could suddenly become the other gender. Fantasizing that you are the other gender during masturbation is also a fairly common sign.
I realize that in your situation privacy may be in short supply, but there are limited ways to express femininity in the real world to see how it fits you -- such as wearing female underwear, introducing female clothes into your wardrobe that are not too obvious, such as skinny jeans and T shirts, and flat women's shoes, like slides or espadrilles.
You can also grow your hair out, and slick it back or wear it in a ponytail when you need to portray as male.
But you should really access some therapy in your own country. Hopefully you have health insurance coverage or the government provides health coverage. Get online, do your homework, find what is available. If you are diagnosed and get on hormones, then you can become the girl you are dreaming of.
