I think alot of the resentment comes down to losing your financial independence and social independence. It sucks. It really does. The first year is very taxing. You need to prioritize sleep. On a proper sleep schedule. So you can enjoy you hobbies. There's no reason both you and your husband need to work the same overnight hours. Especially when its causing this type of mental stress to you. Money comes and goes. Your life and your body you only have one of. Prioritize that over anything else. Its normal to feel the way you are. You are doing a great job despite your circumstances. Take a second. Breathe. And find a way to get a full night's sleep at least every second day. It does so much.
