An animé characther who's personality is almost exactly like your own boy/girl.

i'm most like iwaki kyosuke
we're both embrassed easily
we're both social and kind but it takes a lot to get us to montrer someone that side
we both like to read and act
we cherish our private time
we come off as cold and anti-social
we both work hard towards our dreams and goals
we're both naive and stubborn

sunako nakahara : Wallflower!

I have never seen an animé character who's even close to my personality, but the one who's closest I'd have to say would be Taiga Aisaka from Toradora!.

Italy.

We are both creative.
We have the same color eyes
We are Italian
We l’amour cats
We l’amour pizza and pasta
and more

^_^

There are quite a few different characters with various large personality traits of mine, but I think the character with the most is Mayoi Katase from Acchi Kocchi :3 There is pretty much no area where we are different...

I've always found Nanako-san (Casey in the english dub) to be exactly like me we both l’amour baseball,we both l’amour our teams and we both almost always wear something related to our team..she's the only animé character I think that's close to me.

Toshiro Hitsugaya from bleach!
We are both serious most of the time.
We both have the same zanpakto (mine is a cosplay)
We both have the same eye color
And I like watermelons and anything else that i am forgetting but me and toshiro are alot alike.

Sakaki-san from Azumanga Daioh. Here she is researching chats and where they hang out I think. I tend to spend a lot of time researching whatever it is that has got my interest at the moment, be it astronomy, genealogy, history, Castlevania, anime, whatever.

Iv seen allot of animé characters that share allot of my personality traits, but i would mostly be leaning towards Shirley from Code Geass, id say were probably the most similar in terms of looks aswell.

me sasuke always looking to get revenge on someone

Hm, that is kind of a hard question.
I would say Kotomi Ichinose from Clannad is the most like me since a lot of our personality traits are similar but I have had two Friends tell me that I either act like Anri Sonohara from Durarara!! ou Anthy Himemiya from Shoujo Kakumei Utena for the exact same reason.

i find myself to be alot like Amu Hinamori from shugo chara . Thats the reason i first read the series , ou yaya yuiki from the same animé , mostly for her perspective on "main characters" ou misaka from a certain scientific railgun because of her delicate mind and how she escapes awkwardness .
