Rawbob's advice is excellent.. to which I can only add a little. *I checked your profile. *You are still a teen... so check out agencies that will help you. *Call a teen hotline. *I'd say 3/4 of the battle in getting a job is knowing someone. *Don't be afraid to ask for help. *Many companies offer "first time" deals... for housing and transportation. *There are people out there who can help you, you just have to look for them.
Meanwhile, try not to stress too much. *Remember the old AA motto : "One day at a time."
Good luck and keep us posted.
edit: *Oops... *I didn't notice that Rawbob already used the "One day..." thing. *Hmmm... how about a little prayer or chant for when things get really bad:
God grant me the serenity to accept the things I cannot change;
The courage to change the things I can;
And the wisdom to know the difference.
