Sibling committed suicide

mo

I know this is a child loss group but I just need to vent me and my older sister weren’t on good terms with our mother when our sister took her life a week ago at 29 years old leaving behind 4 siblings and 2 kids me and my older sister had cut her off due to her alcoholism she told us 8 months ago with our mom she was suicidal and was showing changes in behavior I told my concerns to our mother and was met with hate saying I was nosy jealous and needed to mind my own business and she couldn’t make her do anything I just wanted her to check on her so I told my older sister and she asked for her address and she wouldn’t give it to her and our mom turned her against us we made up with our mom but not our sister we all made up around Father’s Day 3 weeks ago except me and my older sister had gotten into another fight with our mom about our sister then 2 days later our sister killed herself and we were put in an awkward position of having to deal with eachother but the funeral ended yesterday and the past week she will not stop sending hate messages and trying to blame me and my sister for her suicide and throwing in my face that I wasn’t in my sisters letter but neither were 2 of my other siblings I’m at my wits end I feel like I’m going crazy I can’t even grieve
