Depressed husband

I’ve noticed I’ve been coming here a lot lately mainly because I have 0 friends who are married . I’m 24 my husband is 23 we have a 10 month old daughter and I’m currently pregnant going to give birth oct 8th ( csection date] . Now that you have a little background on me ....

My husband has falling into a depression he’s told a few times he wants to kill him self only thing stopping him is me and the girls .

I understand he has a lot on his plate between handling bills I’m a stay at home mom , he has some issues with his parents they turned very religious and tend to judge him a lot , then demons from his past .

Im scared my anxiety has been off the wall this pregnancy so I catch panic attacks a lot .

I’ve dealt with my mom being depressed growing up , so I understand how to somewhat deal .

I’ve feel like I failed him because I don’t know what to do or say . I ALWAYS tell him what an amazing job he is doing I point out all his pros . I’ve brought up seeking help and he tells me that’s for the weak .

I should mention in his household having a mental illness was a sign of weakness . We are Spanish don’t know if it means anything but a lot of Spanish people see it that way it’s never taken serious .

I just don’t know what to do I’ve been reading on depressing to understand it better . I’m trying but I keep feeding as if I failed him & the more I feel that way the more it take a toll on my mental health let alone me being pregnant and super emotional as it is

Is anyone going through this ?

Have you gone through this ?

What steps to I take ?

Help please
