Sick of my life being in turmoil.

My fiance' got a new job this week after being unemployed for a few months. Financially our lives are shit. I have a student loan refund check mailed to me they said the 2nd and I still haven't gotten it. I thought it would be today. So I call and they said I'll get it next week. I just break down in tears. My diaper party is tomorrow I have things to buy for it, utilities past due and rent, had to write out checks to get gas in our cars which will now bounce... We were hoping and praying it came this week. He wont get his first pay until next week. I'm just at a loss and feel defeated. Everything always happens at once right before my due date. Always...
