How can I be noticed by my friends?

I want to be notice by my friends. I don't want to be popular or anything but whenever i'm talking with my group of friends, someone cuts me off and talks about something completely different and then every joins in and leaves me sitting there. Believe it or not, even the teacher ignores me sometimes, like when i'm raising my hand (and mind you, I sit in front of her desk, not cause im bad but because I have an eye problem) she calls someone behind me as if i'm nothing but a speck of dust. Please help!How can I be noticed by my friends?
try to be more outgoing. tell jokes. keep a smile on your face. be a happy person. and as for that so call friend that cut you off when you were talking. If that happens again. Stop her in her tracks. Tell her excuse me but I was talking. and say it in a firm voice, show no weakness. and let her know when you are finished talking she can then have her turn. and smile when you say this.How can I be noticed by my friends?
be more aggressive, determined, and most of all make yourself believe your the CENTER OF ATTENTION.
Ask the various people why they interrupt you (ask each of them, including the teacher, in private).
Dress in all black and start listening to Slipknot.sadly this might actually help.
