Ok, so everything changed a bit now...for the better!

Who knows I can close this thread with a good "everything is all right"?
I was really sad and depressed after my last post...I was feeling so lost and I couldn't stand like that anymore.
Here we have a saying (I can't translate very well) that is something like "or it will fix, or it will break". It is exactly what I have decided to do. Or I will fix my situation or I will break it once for all. I couldn't stand on the middle anymore. And I decided to do it by "throwing a cold water bucket" on my parents.
I called everyone for a conversation and I told the subject: my "crazy idea" of transitioning into a woman.
My grandmother started saying that again I am a man and that my idea would go away with time. Then she started with the same arguments: "but your voice is a male voice"
I replied a big and sound "you are very mistaken. It sounds quite feminine sometimes and it has always been this way. I can learn to make it sounds even more female."
She asked me: Who told you that?
I said with a very female voice: My phonoaudiologist. I have been secretly seeing one on the last month.
Then I think she was a bit of in shock that I was really going forward and that my transition was not some "crazy idea", but a reality in motion.
I tried to elucidate things the best I could. I was not trying to explain the causes or why I want to be a woman, but I tried to explain what will be of my future, that my future can be a bright one if they can help me to build it.
I explained carefully that I am can look female with some effort and FFS. I showed her a pic of me with a virtual wig and make-up (the same of my profile here) and then she got stunned: "Is this you? No, it can't be..."
But she realized that it was my face, just with a different presentation. Here she met Natalia.
I could see that from this moment on she got more open and started accepting more that I can have a future as a woman.
I told her that, if I can look like my photo, I may be able to pass and, perhaps, live in stealth. This way I won't be in risk of being victim of a random homophobic or transphobic in the streets (one of my family greatest fears).
She agreed. My grandfather was only listening and he wanted to see my photo too, but he stood mute all the way.
Then I told that I already started my facial hair removal (IPL) and that it is a quite simple and cheap method, and that with some luck I can be rid of my facial hair until the end of the year.
I kept telling them that I am already presenting changes as I am on hormones for more than 5 months. I was wearing a very thigh t-shirt and my developing breasts were clearly visible. I pointed at them and I said: I am already having very visible changes and from these ones (I grabbed my breasts) there is no return, even if I wanted to stop everything.
To end with all, I asked them to not treat me badly again, because they are the only family I have and I need their support.
My grandmother said that it will be difficult for her because she knew me her entire life as a boy and that she have never suspected of anything...but she didn't try to discourage me anymore. She even told me that my eyebrows won't need much work and finished saying "so you are a woman"
I could listen on her voice that she was being a lot more open and sincere.
At the end of this conversation we stood together having a very nice talk about other unrelated things. I said good night and all returned to normality. My grandfather, besides being mute almost the entire time, was also being receptive and didn't treat me bad.
So, I think that my hopes were right! I am now feeling A LOT better and I am just not feeling even better because I am afraid that tomorrow things might change again... I'm just not believing that everything went so fine this time...I hope I am not dreaming!
I want to thank every one of you that helped me with advices and incredible messages that helped to cheer me up every time I needed. This support was essential for me to be where I am now. I it wasn't for you all I don't know where I would be. A huuuuuge hug for all of you! Thank you! ^^
PS.: I hope this is my last message in this topic and that from now on I have a place to run!
