IDK!!!!

I don't know what to do, Lord...which way would you have me to go?

Ok here is my dilemma, yall:

I love my job, but I maybe leaving it soon.
I need a car, but I have NO money.
I have the best job I've ever had and my rent is beyond reasonable, but I make $300 less than I need to a month.

This was not so two/three months ago...I was thriving...I don't get it.
WHAT AM I DOING WRONG!!!!!!!!!!!!!

And just as important what must i do to fix it? IDK!
