I just found out all my coworkers quit??

I literally just got off work and OH MY GOD! I was closing with my fav manager and a diffrent coworker who is my fav coworker comes in to order something into the store and she mentions my managers last day?? So I ask what's up and apparently she quit! Along with the manager i hate quit (solved the problem from my earlier post ig??) because she did! And so did my fav coworker! And my assistant manager left like twoish weeks ago? So it is just me and one other girl rn and I am so nervous like i liked all my coworkers and now I'll have all new ones?? And I have another job sorta lined up so low key might cut down my hours here since the other job would pay more
