NEED HELP

:cry: I'm a diet mtn dew addict and trying to kick the habbit. I also want to try to quit smoking too . But dont know how to do this with all stress in the house. I have a step son with developmental delays, emotional disturbances, and is on the autism spectrum . He is 14 and now in trouble with the law because of theft. He started stealing pencils and stuff from school when he was 6 and at age 12 he snuck to a big store stoled 500 dollars worth of stuff and had to write only appology letter and not go into store for a yr. Then after that he stoled a belt in the school from a child that was in gym class, then went swiming with his counsalor and stoled a 200 dollar watch and had to do a program community justice. Now this yr right after christmas he went to another store and took off on his father and stoled a 20 dollar watch and he got caught this time by a cop. Had to go to court for that and now still more court stuff for him. Then i have him lying when he dont get his way saying I or his father beats him and gets social services in our lifes. He has done this for 9 yrs , And i have a husband that doesnt parent and acts like he is his son best friend. And the son is lazy will not wash up so hubby has to go into bathroom and watch him shower to make sure he washes. And hubby usually makes exscuses for his son. So doesnt hubbys mother. So it is very stressfull in my house and only thing that keeps me from blowing up is smoking and the caffeine.
