Sassy, what your going through must be Hell. No mother should be in a situation when they outlive one if their children, and it's horrible when if happens.
People can really be so insensitive. My eldest brother commited suicide a few years ago, just completely out if the blue. I was away when I found out, but my poor mother was entirely on her own when my SIL called to tell her (I was away, my dad was away my other brother lives away) and the thought of how she must have felt when she was told the news, in some ways, hurts more than when I was told the news.
My other brother was hugely I'll as a child with kidney faliure. He had a transplant in the nick of time, but he doesn't have a long life expectancy. He'd battled depression for many years and my parents had always worried over his mental health. My oldest brother had it all on a plate really..good job, wife, great lifestyle. Something went seriously wrong and that was it, he just killed himself, we'll never know why.
The most awful thing about if all was hearing my grieving mother saying with such disbelief that she will eventually outlive both her sons.
In the while after my brothers death, do you know how many friends asked me how I was doing? One. That's it! She will never know how greatful I was to her asking me. I have other friends, some of whom I am very close to who have never even mentioned it to me at all other than in a "sorry to hear you'd bad news" text at the time of his death!"
i've not taken it personally, I've just learnt that people are really, really fucking shit when it comes to making conversation with someone who is grieving. Ans especially someone who is grieving over an unexpected death of someone who didn't die aged 93 peacefully in their hospital bed in their sleep.
2 months is not even time for the fog in your mind to even begin to lift so please, please look after yourself and don't waste your emotions on well wishers who are dithering around putting ther foot in things (all be it unintentionally)
I really wish you well.
