Is this... bad?

So here's the thing, I've been throwing up everything I eat. No, I'm not bulimic. But, everytime I eat something, it comes right back up no more than 15 minutes later. In the last week, I can just tell, I've lost a lot of weight and I've become a lot...

weaker and dizzier. Is this something serious? See, I can't exactly tell my parents, they'll think I'm drinking or on hard drugs or something. I don't know, they just don't trust me.

So any doctors or anybody with medical experience that might be able to help me out?

Or people that aren't doctors, and just wanna try to help me out. I'll listen to anything. Cause, this is just very misserable...

ask a grandparent ?

because you should go to a doctor and if your parents wont take you, ask another family member

ask someone you trust. but I really think you should try to hold it down. and I mean come on, if you have noticed that you are skinnier and everything, shouldn't your parents notice it? maybe this is the time where you and your parents need to come to an understanding. if this sickness with you becomes life or death (don't want to scare you but it could happen), then you don't want any regrets. and as much as they don't seem to understand you, you are their child and they do care about you. so I would say tell them and if they don't believe you tell a best friend and have her mom take you to the hosipital. if you are hospitalized your parents will realize that they were wrong to judge you

You need to see a doctor, you could have any number of things wrong with symptoms like that.
Tell your parents and go NOW. Something is definitely wrong. ;/

Btw.. I am a nurse. Although I can't, by law diagnose, I can say that with the symptoms you have it could possibly be quite serious. Just start out telling your parents 'first of all, this is not caused by drugs or alcohol--but I need to see a doctor and then tell them what you posted here.
Also, is there ANY chance you could be pregnant?
