I don't know what to do 😢😔

Well...

My parents have been treating me differently lately. They treat me like I'm not worth anything and I'm the oldest of three girls. I had a soccer game Friday and didn't get back till ten at night.. and they weren't home and neither where my sisters. I called and no answer from my dad or mom.. I went into their room and there's a note saying they left to Mexico... I called my boyfriend because I didn't have anyone else and I was scared and when he got to my house I showered and so did he .. and we layed down and I cried all night because I couldn't believe it...my parents have been ignoring me.. pushing me away.. and I'm just 16..😔 My boyfriend said that if it keeps happening he will take me in with him and his family.. but what about my family? What will I do? What did I do wrong? Where did I go wrong? .. 😔
