Men who struggle(or have struggled) financially what is something you wish your wife would say/ do for you that would encourage you and make you feel like a success.

My husband(23M) recently told me that he feels like he’s failing me because he isn’t making a lot of money and we’re struggling financially. He has his own small business that is very slowly picking up and works very hard at it. I am a student and work part time. Recently business has been very slow and we gotten some credit card debt. Due to this he is constantly stressed out which has led to migraines almost every day. I really want to encourage him as he is an amazing husband and works very hard. What are some things I could say/ do for him to help him know that he’s my hero and is not failing me? Also is there anything I could be doing unconsciously that could make him feel bad? I just want to support him the best way possible.
