Help :-(

So Im 20+4 and today my husband cones home and tells me that his company got sold. Its a small franchise where only 5 ppl work. I had a bad reaction basimcally telling him this is really bad and he may lose his job. He said its a good thing snd everything will be fine. He says his boss told the buyers thst s stipulation of selling the buisness is tgat they kerp all the staff.  My hubby trusts everyone...i dont. I know everyone is only out for thenselves, especially in buisness. Now i cant stop freaking out and crying. I know its bad for the baby but i cant believe this instsbility is being thrown on me right now. Hubby isnt talkin to ne cuz i freaked do much. How can i calm down?!?
