Skeeter so sorry for you. It's important you look after yourself you won't want to eat but you must and drink and make sure you take any medication you are on. Life doesn't feel real and you can't see a way forward. But you need to keep your body strong. As you are going to have to make a lot of decisions in a short time period. Your grief is overwhelming and the last thing you want to think about paperwork but unfortunately it has to be done. I hope you have family support.
Talk out loud to your husband everyday I promise it helps . Scream ,shout,swear hit a pillow just don't hold your feelings in . I did that and the only person I hurt was me. But I was 45 at the time and thought I had to be brave I was a fool. I am now 65.
Your husband wouldn't want you to be brave and he would want you to look after yourself. Love never dies even when the person you love dies. In fact I love my husband more than ever . And so glad I was loved and loved in return. As your husband loved you and you loved him.๐น
