Hardship in a new country

Hi, thank you for taking the time to read my story, I was raised in Texas since 7 years old and eventually bybthe time I was 16-17 started doing things with friends that led me to break a law. Às I was being helpful always doing favors I got caught up and involved in a burglary which revoked my imigration application and after years of fighting the case I got denied affidavit and convicted, therefore I was asked to leave the country back to mine. Mexico. I dont have immediate fanily here, i had to bring my children and It is hard to trust anyone with them. I worked for a CA law firm over the phone acheduling appt but they background checked me. I am to the point of no food in the fridge and request any kind of help. Thank you
