I am sending you many good wishes of luck.
Also do not let ones that question where you were, in that "not sincere way", I had a similar situation back in HS, and I was new there, bullied, pushing me into being a "quiet and shy person", and even being that way seemed to attract more bullies, etc.
Believe me, my teens were not great at all, like others claim their's were.
But my words of optimism, you can get through this awkward time in our lives, so many of us have survived it and went forth in this world, for me the 20's were the begining of a happier me, making money at a fairly good job, independence, feeling like a true adult but still young

It seems since the time I graduated HS and walked out those doors for the last time, life was less bleak.
Sure over the next years to come you will have ups and downs, but keep your head, you can make it through

Again, lots of love and luck to you
