Should I to return to Mexico?

I came to the usa recently from mexico but life her is not what i expected. i have been here for a while and i gave it some time but i feel that this is not the right place for me. it is very difficult for me to interact and deal with other people in the usa. my speaking english is getting better but i do not fit in anywhere. i am feeling that people in the usa are to busy and to woried about their own lifes to think about there fellow man. people do not to become my friend. they are to concerned with there own matters. people it seems, do not know how to have real human-human connection and they do not know how to have a dialogue with meaning. i sometimes believe that i should return to mexico where i did not make so much money but i did have family and many good friends. i have understood here in the usa that haveing money is not the best way to approach life. i am not happy even though i have so much money here when compared to mexico. i want to leave but i have kids here in the usa and they are adjusting to become real americans. i am also worry that my kids are getting bad influence and bad role models. i am lossing respect for the american people. i do not agree with there morals or priority. i do not want my kids to develop in such a place but i know they have more oportunity here. sometimes i just feel it is not worth it. i might want to be poor and happy instead of rich and upset and unhappy. should i go back to mexico afte r my kids leave the house? i have two sons still in the house but they are leaving soon since they are aproximately finishing high school.
