I think if both parents have depression, they should try their best to recover on their own. I believe that with the psychology that parents love their children, they should be able to overcome this acquired depression.
The most important thing is not to force yourself to recover, to communicate with your true thoughts, not to give yourself any pressure, to conform to human nature, to drink water when you are thirsty, to sleep when you are sleepy, and to calm down your body and mind first. Don't be paranoid, don't worry too much about the future, and don't pay too much attention to external information. Sometimes, the more sources of information, the easier it is to disturb the heart, but it will cause more trouble.
Learn not to care too much, first of all, learn to let go of your thoughts and don't put pressure on yourself or your children. A family can listen to their favorite songs, sing songs, walk outdoors together and forget all the unhappy past.
Learn to have love in your heart, feel the power of love in your heart and live in the simplest way. Having the power of love can really overcome many psychological problems.
If children have grown up, they should take care of their parents with their sincerity and warmth, be considerate of their parents, and help them overcome their pain with sincere heart. It is reasonable to know that "sincerity can open the stone"
First of all, I don't advise a depressed person to marry another depressed person. This is a psychological disease, not a physical disease, so it is not good to help each other in the same boat, and it is a bit high to get along with people with depression.
If both parties are really depressed, they must go to the hospital for treatment. Otherwise, it is difficult to guarantee that children will not be affected. Of course, it may also be a naturally happy child, infecting parents with their children's happiness and giving them the motivation to continue living. However, parents should try their best to educate their children after overcoming depression.
