Loss of husband

After being married 49 years and 9 months, my husband passed away.  He went in for pre-op testing because he was having a second knee replacement done.  They found two blocked arteries - one was 95% and the other 80% plus he had an aneurysm by his heart.  He needed open heart surgery.  The doctor was very confident and didn't foresee any complications.  Unfortunately, people are not always right.  My husband was bleeding and he wouldn't clot.  I still don't really know what that means except that he is no longer with me.

I feel so alone even though I have a daughter.  She has her own family to worry about.  I have a brother in law and sister in law who try helping me whenever they can.  My friends are there to listen, but have their own lives.

I just cry and cry.  I know he wouldn't want me to be doing this, but I'm just so sad.  I miss him.
