Insurance after cancer?

So, now that I am in my fourth year of the life altering even of cancer, I am finding that I have to search for new health insurance. This has proven to be a miserable experience. Insurance agents lie about what they can do and what they can't do to get your information why? Because my husband, who is in wonderful health is more insurable than me. Everyone says Obamacare is supposed to help with this dilemma but, it's not. I've been promised time and time again that if I get this piece of information that they should approve me and then they don't but, suddenly Robert has insurance weather he wants it or not, usually not. We make it clear to the insurance folks we don't want the insurance if I'm not apart of it and somehow they force him to have insurance. So it becomes a long drawn out process to get our money back.
