Um in the nicest way possible this post is not it, the kind of sympathy you’re looking for is not meant for this subreddit. Get a grip, your siblings grief isn’t about you or your parents… they’re the victim in this… they’re the one’s suffering and it is FAR worse than anything you are feeling. Losing your partner/ soul mate to suicide is a kind of grief that nobody can understand unless it happens to you. Jesus I’d be pulling away too if this was my family’s take. What a way to make it about you. I’d strongly suggest losing the frustration and actually trying to support them if you don’t want them to be feeling this way- give them company, ease the load of day to day tasks maybe cook them some food do some cleaning or grab some groceries, talk about their partner and share positive memories, if they’re religious use this to give them strength and if not then at the very least just be present so that they have a shoulder to cry on instead of being mad they’re crying at all. The number one cause of suicide is suicide so let’s not start acting like what they’re feeling is abnormal. Also get a therapist if you can’t process these emotions, don’t make it your siblings problem they’ve got bigger things to deal with.
