Horrible Feeling; please help.

So a month ago my mom took me to the doctors cause I had a horrible cough and he scheduled a check up. When we went to the checkup I told him about my periods and he put me on birth control. Everything's been fine but yesterday i missed it because I take it at 9pm everynight and navy ball was during that. And i was told to just take two the next day. But i took them an hour early because i felt like passing out and I was already a bit sick the previous week. And with a big family fight on abuse I had cried earlier today.With the crying ontop of that and now my body feels horrible. I've been drinking water but it hasn't done anything. I texted my mother about it and she genuinely didnt care. I didnt really know where else to go, I'm only 16. Do you guys know what I could do to help any of this? Am I perfectly fine?
