stressed out. relaxing techniques?

So I have a little under 34-35 days to go until I get induced, and every little thing that comes up, sends me into a tailspin and I freak out. Like, we have a car repair coming up because my husbands car failed its emissions test and we don't know the repair cost. Husband and mechanic knowledgeable friend are very conifedent it won't be terribly expensive. But I can't stop thinking about it. And today, my boss isn't responding to anything and I need an answer before I move forward with something I was assigned. And I am just so frustrated because I feel like I can't relax!
