my parents dont notice i exist until i do something wrong. if i get bad grades or get into trouble at school they are all over me but when i want to talk about me whats going on they seem to zone out completley. its not like that with my other siblings though and i dont understand why? maybe its because im the oldest or something but that still isnt right to me.

Well, try telling them that. Maybe they haven't noticed this.
So let them know that you feel kinda left out, because they haven't been giving you much attention.

Simply, talk to them. They really care for you but you just need to sense there love. They are also trying to "hover" over your siblings. This is extremely common among my family, and I have gotten use to it over the years,

I agree with Bo Talk to them tell them how you feel

You could also talk to your siblings about it.

I'm the littlest in my family, and I feel EXACTLY that way! In my family, anyone will cut in while I'm talking and attention will immediately divert, and it doesn't seem to matter how important the issue is either.

About parents not noticing when you do something right - I bet they do. I used to feel very insulted and discouraged because I was treated that very same way too. The day I moved out though, my parents sat me down and kind of explained. It didn't really help much - I felt like shit the last 6 or 7 years and nothing solved that. But my parents did acknowledge and specifically congratulated me for being resourceful and taking the initiative to find (and get into) a good college, and I definitely had my life much better sorted than people my age.

I don't think it's right for you to demand your parents to include you more and acknowledge the stuff you do well. You do have to realize that your parents want you to be the best possible person you can be, and for that they'll always be on the lookout for things you can do better. It's discouraging at times, and you'll also feel very lonely when their attention goes to your siblings. It's extremely common but if you're ever down, we're all here to help talk things out :)
