husband is taking a job that makes LESS

Let me start by saying we have 2 kids. Well, one is on the way. I'm on bedrest for the rest of the pregnancy, doctor said under no circumstances can I work. My husband lost his job making $25/hr. Now he just started today making $9/hr. But they will let him work 80 hour weeks and that's enough to make it work. 
Instead, he's quitting to go work as a mechanic because that's what he loves. But they only make $11/hr. And it's only 40 hour weeks. The hours he will work are going to be hard to have a part time job as well. We are on the verge of losing our house and being homeless as we have no family. We signed up for assistance but keep getting denied. Am I right to be mad? He's saying I don't care about his hapiness because he wants to do that but it wont make near enough..
