Scared, frustrated, just generally upset

Yesterday, I lost my job. This is the first time that this has ever happened to me. Was I terribly attached to it? No. But I was attached to the paycheck it was going to bring in. Thankfully I'm starting my new job in a week and a half, so I won't have to go for long without work, but it does mean that I need to figure out how to come up with money for the next month before I get my first paycheck at said new job. There was no real explanation given, just that the management had decided that it would be best for me to start my new job early. I wasn't allowed to finish out the week, I wasn't even allowed to finish out the day. Just told to pack my stuff and go home. I'm trying to remind myself that God has everything under control, but that's not the easiest of things to do. Prayer right now regarding this would be really helpful. :)
