Financial panic

6 months ago, around Christmas, my bf found out that I had relapsed when my uncle died the month before. He left me. He was the only one that was keeping the 3 kids while I was at work. So, I had to stop working. I called my dad in my home state and told him what happened. He begged me to come back. So, I used my last paycheck to get me there, on the 31st. He overdosed and I found him in his bed on the 2nd. We hadn't even been there 2 days. So, I came back to Indiana, and got a hotel until I could find an apartment, got my job back, got someone watching my kids, etc. Last month, my babysitter had to quit. I don't make enough to put them into daycare so I applied for vouchers through the state but I still haven't heard back from them. I had to stop working, we are still living in the hotel, and I don't have any money to pay for it anymore. I applied for unemployment, filed for child support, started doing side jobs, am trying to sell stuff, anything I can to make the $300 for this week. We have to be out by Friday morning. Tomorrow is Thursday. We have no where to go, no one to stay with, none of the shelters here have openings...no one back home can help me...I can't borrow money....I'll have started the contracting work I set up on Monday, and the guy is supposed to help me out by giving me money Monday as well because he knows what kind of spot I'm in but I'm about to be sleeping on the sidewalk with 3 small kids and I have never been this freaked out before in my life. I feel so awful and alone and Worthless because I messed this up so badly. I have been looking online for hours trying to figure out somewhere I can call or email or go to for some type of help and I have some to go to tomorrow but I can't seem to calm down. So I figured I'd write something out and see if I can calm down. It's helped, a little...
