I cant find a job my girlfriend is pregnant and we have no where to live,what do i do?

okay so my name is dustin, i am a former tattoo artist but quit to have a family. me and my fiance was told by my mother that there was work in PA so me and her packed our things and left SC and ended up at a red roof in living in the same room as my mom and her boyfriend. my first day i got a job as a salesman but after three weeks of seriously doing all i could there was still no paycheck. so i decided to find work else where. i have filled out about 20 apps a day for the week now. and still do not have a job, 1 interview comming up. now i had planned everything would work out. but my mother (and im not going to slander her though i wish i could) has been getting intoxicated everynight and starting serious fights and arguements its getting way out of control. so now me and pregnant girl have got to find somewhere to live, and i am still working on the job situation, i can no longer live her we have burned all of our bidges and now we have no where to go. she is due in april and to be honest i hate putting her through this!!!! i cant join the military due to one stretched ear and cant afford to get it surgically fixed. WHAT DO I DO??????? i am no bum i am no lazy i have exceled at every job i have ever had! just unfortunite events caused me to go else where. i am really scarred and would really like to know what i should do?
