Husband can’t get a grip

Problems = he can’t cope and I don’t know what to do.

Recently my car failed mot and need to pay £250

Husband has changed jobs (he’s just handed in 4 weeks notice) he accepted a new job it’s further away and means very early mornings I will be driving him there as he doesn’t drive he starts in a month he starts at 5:50am we will need to leave the house at 5am. He will need to wake up at 4;30am so he can do a poop.

I can cope with change I just adapt, he on the other hand has huge out bursts of stupid anger and complaining but he goes on and on.

I don’t know what to do. He doesn’t cheer up. He just adds more and more problems into his head and says I don’t want to live anymore.

Meds aren’t an option so please don’t advise getting pills.

I’m asking how do I get him to grow up and get a grip??

I’ve been through hell in my life and have coped with stuff out of nightmares so the way he acts really angers me unfortunately and just makes me get mad I try to advise him and give him thought processes but he doesn’t listen. Help
