Seasonal

So I was hired as a seasonal worker October 24th, I've worked my ass off everyday even came earlier then my sups & managers so I would always be the first person they see. When I say work my ass off I mean literally work my ass off. I worked as a pre loader and they even had me work almost every position in the building. Last week or so one of the managers come to me and say "congratulations on your permanent position!" Then I ask my sup if that's true and he says don't let anyone get your hopes up. Then they tell me last Saturday that's it's my last day at work then literally call me next day to come in. Then they say that the 15th is last day for seasonal employees. They also told me that they put me on the list as "yes" to come back to work as a permanent but that now I should reapply to any positions once they pop up for my hub or to be on the look out for a email or call from HR or my sups. Honestly loved the company and gave them everything I got they even had me breaking my back for them sometimes and I just feel like they gave me a run around. Don't know who to believe at this point or what's gonna happen. I'm in my young 20s with 4 kids. Should I be worried or have some type of faith? Btw this is a Florida Hub.
