teenage years are brutal, regardless of race, location etc. being a teenager often just sucks. its hard enough dealing with all of the emotional stuff that comes with being a teen, let alone trying to make a fresh start where you dont know anyone. i think its perfectly normal that you feel this way, and i am so sorry. I do think you should speak to your parents, but i have another option- im australian so i dont know how it works in the US, but im a high school teacher. i often refer kids to the school counsellor, who keeps your conversations private. they dont notify the parents about the counselling unless there is abuse, suicidal thoughts, self harm etc. do you have a school counsellor you could speak with?
I know 3 months seems like a long time and it feels like its dragging on, but i think in time, you will make connections with people who realise what a valuable person you are. this can be a slow process, but hang in there. dont give up and dont give in. you are not alone- i teach many teens who feel the same way you do. and hey- i remember high school. it can be a daunting place. i would consider the school counsellor, or finding a way to let your parents know how rough it is for you. i do also think you need to give it more time.
Im sorry, i know its a crappy feeling- keep us posted,
