Ehh.. alright, I'm not trying to be emo but I need some tips or advice when I feel like I'm low on cash

for example.. at this point... I have about 500 in my bank(after I get paid) and I'm feeling a little depressed after recieving 2 parking tickets.

I can't get anymore hours where I work because "I don't sell enough" and I'm looking for a new job but it's tough.
