MY experiance between countries

As you can see from my profile im half japanese and basically half american because thats where i lived at my entire life. I was just born here in okinawa my mother is from there and my pops is american he was in the miltary then. But having japanese citizenship and not speaking the language or knowing the culture or not even looking asian japanese i took more of my father side. I feel like i dont belong in my home country. I didnt choose to come here like so many people that did but like to complain i was deported because my permenet residence card was revoked because of a incident with the immagration DEPT. I been here almost two years and struggling to keep my head above water to survive because im talented in many areas but i can not speak the language so im limited in japan. I just want to meet the people who can relate or in the same situation or even from anyone who can give me advise in how to be succefull in japan. Im a decent person good attitude good people skills i teach in elementray schools and highschools so i do like kids even though they can get on your last nerves the older ones but i have fun i just want more and to be what im worth im tired of meeting with fake people that complain about being in japan if its so bad go back to your home country then.
Anyway im doing o.k. and enjoy some of the things i experianced. but cant get through the the things some of the japanese culture or what ever you call it because how i see it japanese people tend im saying not all but the majority are some what prejuidice or even racist to someone who is not 100% Japanese and thats what bothers me the most theres more to complain about but its understandable and workable just that one thing hurts and gets frustrating. Anyway anyone who is or can comment on this would be great.
