How to keep my stress low?

Dr
Brand new (to us) Car broke down, shot the engine, cost 300 to tow hubby lost his job and I'm pretty sure we conceived. He has a interview next week for a very nice job and we are both nervous about it. I don't want to stress out and miscarry if I'm pregnant. Any ideas or things that help de-stress. I tend to just bury my feelings but I know that's not the right way to deal with it right now.
