JazakAllah 
I have the same exact feeling, many people tell their parents right away, become these amazing people, and everything works out great. Nobody really knows I am Muslim, and that is because, honestly, I am too scared to tell them.
No reverts path is easy, and I know I said that sometimes everything works out great, but every revert to Islam has gone through many troubles. Listen, Allah SWT knows what you are going through. You do not have to quit everything all at once if you convert to Islam. You can take small steps, and maybe even eventually just mentioning to your parents that you are reading about Islam. I would never actually say that you converted, because that makes it seem like you went through a huge ritual and are now stuck in one religion for your whole life.
The Prophet SAWS once said that Eman (faith) comes in waves. I know that the hard way--my Eman wavers dramatically from day to day, and the littlest things can affect it. Sometimes, I will be so elated on faith that I will say I am going to tell my parents that day, other days I think that I should have waited longer to convert to Islam, or start to question my belief in Allah SWT. And I do not know if that is because I am a teenager or it is normal I am the kind of person to hide from confrontation, which I think that you might be too. It feels like you will never ever be able to tell them, right? Well, I am in the same situation. My path has not been easy, no one's has. And that is why you have to have Sabr (patience) in Allah SWT.
Have you heard of the story of the Prophet Yusuf (PBUH)? He was tossed into a well by his jealous brothers, worked as a slave, put into jail for ten years, and eventually he was able to see his beloved father again. So, there is no real answer to what you are going through, but there is no wrong one too. Do what you think is best for you, and your faith.
The most important thing is to make duaa. Make duaa (prayer) that your parents will be guided, that you will have enough strength to tell your parents, and Insha'Allah Allah SWT will answer your duaa!
I really hope this helped inshaAllah!
