irish decent

I have found out recently that i am irish, that may explain my temper, my love for learning gaelic, i have been studying it since i was young, my family always ate irish foods, and had accents, but they would never tell me i was irish, or that they were irish. am i crazy, or was my family ashamed of being irish, i am very proud of the fact  that i am irish, i love ireland more than america, i would def die for ireland before i would this god forsaken country, people always ask me if i am from there, and i have to say no..

i feel ashamed of that. is that wrong? and would it be wrong to say i am from there when i wasnt born there? like i said, i am irish and damn proud of it, and those who disagree can pogue mo hoin. any advice would be good. thank you.
