AITA for refusing to answer any questions about my husband's death after my adult children said I should be embarrassed to be inquiring?

My (56F) husband died 2 weeks ago from a heart attack. He was only 52 but he had several risk factors. I have seen a couple of lawyers in in order to get his life insurance, but they have obviously asked for more information. When it comes to his doctor, I know his primary care physician but he was seeing a cardiologist, so I don't know his cardiologist's name or any information from him. So I asked my children (21F and 24M).<br><br>They are both married with kids now, and I did a dinner on Monday and asked my daughter and son in law, my son, my daughter in law and my children. My daughter and son both said I should know this information and should have it written down somewhere. My daughter in law and son in law said a mom doesn't know this stuff and gave me a hug and helped me figure out the cardiologist name and how to get the information from him. <br><br>The next day, I thanked them and headed home but my son pulled me aside and said I should be really embarrassed to even be asking my children, of all people, this information. He said I should have written it down right away after his death and that I'm a irresponsible wife for not knowing this. <br><br>I told him there was nothing to be embarrassed about and that he shouldn't be yelling at me for asking for the information. He told me I should have all that information written down so my kids don't have to see getting information for his life insurance. So I said it was done and I would never ask them for anything like that again and just headed home. <br><br>Next day, my daughter called me and said she was so uncomfortable with what happened on Monday. She said I should be more aware and not have asked my children for information like that and that my son was right to call me out on it. I told her there was nothing to it and to forget about it and she said she was embarrassed for me and that I should be too. I'm not really sure. I asked my daughter in law and she said she felt bad for me because a mom doesn't know this kind of stuff. I don't know if I was wrong for asking them. AITA?
