Husband fired, and so depressed for months?

My husband has been a successful attorney for 10 years. He was a total rock for me, helping me so much in my career as well. However, we just had a baby a year ago and about 3 months after having he baby he was fired. They said it’s because he was unreliable - He wasn’t losing cases or dropping the ball, but was taking a lot of PTO to take care of our sick baby. Again, was fired, he says that’s the reason and I believe him. He says that it was because he made a high salary and the we’re looking for cheaper attorneys fresh out of school they could pay half as much. All makes sense. What doesn’t though is that now, 8 months later, he won’t even put his resume together - he’s been obviously very depressed. Every time we try to put his resume together he starts to get emotional and cry. To add to this, he sleeps a lot, and I’ve noticed over the past few months specifically a glaze has set over his eyes.. he’s stopped engaging in conversation, we’ve stopped being intimate except for the occasional thing. He never initiate conversation anymore.. to top it off, he’s been drinking a lot, has stopped helping clean the house - but does focus a lot on taking care of our baby. Recently a month ago, he told me he had 7k left of savings and yesterday he told me that he messed up and only had $500... AND now, he’s started uber driving at really odd hours.. I believe he’s uber driving.. but there are a lot of things that don’t make sense. I’ve asked so many times for him to tell me what’s going on and it all comes back to him being depressed. I asked where the money went and all he will say is “I messed up” he’s in counseling now .. and when I ask him how his sessions went he keeps making fun of the psychologist, he thinks the psychologist is a quack.. he was truly my best friend at one point And I have vowed I’ll never leave him, I do still very much love him.. but he has turned into a totally different person, when I’ve asked what’s wrong he just keeps pointing back to being depressed about being fired.. there are no other variables to it in his mind. I’ve lost my job before too, known others that have and have never seen someone with so much schooling and experience, and smarts, who is totally capabale - go for SO long, and blow all their money, and have zero drive to get back into the workforce. Lately, the lack of engagement, dissassocistion and his lack of willingness to talk has me so concerned that I’m worried either something else is going on or he’s so so depressed that he can’t see straight. Anyone had a spouse, or experienced something similar? He won’t share his feelings, wont take steps to improve himself ..where do you go from here?
