First, no-one can tell you that you shouldn't have certain feelings. They can be unhappy about your feelings but that is not the same thing. It sounds like he's fine with the current situation, you are not, and he's telling you it's your fault that you don't like it. You are a human being and have your own likes, dislikes, and problems and he needs to take that into consideration!
First thing you need to decide is if the situation is causing harm. Is it hurting the kids, your marriage, or you? If it is causing harm it isn't just a matter of hoping the feelings go away it is something that you need to do something about.
Put your energy into figuring out how to get into a different situation for example living somewhere else, getting a job yourself even if it just pays for day care, etc. It sounds like the only thing you are looking forward to is getting back to the days when your husband worked, you lived alone, etc which isn't going to come back. You need to have something concrete that you can look forward to and you are the only one who can decide what that thing or things is and how YOU will work towards it.
In some ways it sounds like you feel that someone else has taken away your good feelings even if it is just the circumstances of your life but good feelings can come from simple things and you need to figure out what those things are for YOU. You presented a list of things that don't do it for you ("me" time, medication, the place) but you'll be stuck doing the work figuring out what does work. It might be getting a job, or joining a group, or marking a calendar and saving pennies for a few hours here and there of time alone with your husband.
The flip side of having your own sad feelings that you can't be told to ignore is that you also have your own preferences that you can explore and they are not all going to be pipe dreams for million dollar houses and caviar. Think about your happy or successful or proud times from the past and see if they give you clues to what you should do in the future.
