I haven't left... Just another vent

I just don't have anything to say, I haven't weighed in now for weeks I don't want to I'm too scared and I know I've lost nothing, probably gained by the amount of junk I've been eating all the time & I'm just so stressed out because of B not having a job!! Work is stressful because One of our senior hairdressers just left past Saturday he got the sack! Then there's this fat body of mine indulging in fast food take out and deserts! Argh!!!!
B doesn't seem the slightest bit interested in getting a job, it's really pissing me off! His not looking and my stepdad offered him something but he wants to turn it down!! Seriously! We have rent to pay every month!! Yet he prefers to be a cleaner with One of my most annoying friends in the city with no proper scheduled days, u get called when to work, when this guy needs him which is hardly ever his worked one day in the month or so he got sacked!! I'm so frustrated! He smokes weed all day and has 3 broken down cars sitting around the house which will probably never run!
I don't know what to do anymore i think I need to start thinking bout ending it all cause no matter how many times I speak to him nothing ever changes it does for 3 days and it's back to normal again. I ask him to do things at home while I'm at work.. Get home 1 thing out of maybe 3 or 4 has been done!! He never answers his phone when I call or replies back to texts! I'm so sick of chasing up after him trying to get a reply, the money he does have which is hardly anything at all at the moment goes to weed, stupid smoking devices and crap like headphones, weird lighters etc! I can't trust him with anything, he seriously flips shit when I even touch his phone, sometimes I look through it & find nothing so idk y he freaks out... *sighs*
Don't know what to do.. Help
