Here's the thing

I  left my family at the age  of 21. haven't spoken to my parents and my elder sister since then. I'm 28 years now.Growing up me and my sister  were close.  I never went to her wedding even though she wanted me. I didn't go  because my dad was going to be there. That was the last time we ever spoke. She has a kid now.

My wife passed away 9 months ago and I can sense I am losing my mind and my overall behavior is damaging in the long run. I am a functioning alcoholic but to tell you the truth I don't care at all.

My wife wanted me to make amends with my family especially my sister.  My question  to all of you is how will you react if  you were in my sister's shoes and I would have tried to make contact after such a long time. I  don't want to tell her that I've lost my wife straightaway. She doesn't even know that I got married. I want to tell hew about my wife eventually but I don't want it to be the origin of our conversation even if the whole thing doesn't play out.
<bot>: haven't seen my sis in 7 years. Missed her wedding. Wife died want to talk to her. She doesn't even know I was married
