I'm a 15 year old girl,this all started when my dad got drunk and started to throw up but at that time I thought I was just grossed out about it and thought nothing of it. Then the next day i felt nauseous again like i wanted to throw up but i didn't and i felt that way for the whole day but I did eat but i ate later in the day because I have been busy moving.So, I was hoping for this to go away but it didn't i felt the same way again but this time i started to get headaches but i was given medicine for it and i still ate breakfast and lunch but i rarely eat dinner most of the times ( i don't know that could be the reason).Then I felt the same again and told my mom about it and she gave me pill that's for nausea but it kinda helped like i didn't feel as nauseous but just a little and i still ate.This nausea has been affecting my sleeping schedule and my appetite. I have been told to make myself throw up but I'm to scared to do that,or I'm trumatized about what happened to my dad and it's all in my head .At this point i don't know why I'm feeling like this but I was thinking i should go see a doctor if this continues,but if you have any ideas what it could be or what should i do please tell me.
