I recently lost my job too, but I wasn't about to tell everyone here about it while drunk. I have friends who are homeless. Yes, homeless. He was an alcoholic for 20+ years and his girlfriend a crackhead...though sometimes still is currently.
Basically, your situation could be a lot worse. My alcoholic friend, I'll call him LL, he decided enough is enough and started AA meetings and got a sponsor and all. He relapsed maybe once in the past 3 or 4 months. It's doable. He's happier than he's ever been in a long time. He's even gotten his creativity back and wants me to illustrate a childrens book for him. He's so incredibly excited about it and beer is the last thing on his mind.
As for having no one, I'm sure you must have family. If not, seriously, AA, grab a sponsor, they'll be your best friend and help you through whatever you've got going on.
