My mum died very suddenly when I was 12. Fine one day, suffering from headaches that was all, the next she suffered a hemorrhage and i got to see her for a short time, brain dead, on life support before they turned it off.
It took me a long time to grieve, pretty much all of my teenage years i suffered from depression, self harming, mental health issues and such. Became a mother at 17. Now I cope by just loving my children and trying not to think of what could have been, it only hurts.
I get scared sometimes thinking it could happen to me, and what my children would go through if i was to die. I get sad sometimes when I'm bustling around after my two children and i think, is this what it was like for my mum? because i feel more of a connection now with her as a mother struggling with day to day things. I found out some details recently which were very upsetting, i tried my best to process them, let out the grief and then "put it away" so to speak.
I enjoy speaking to my aunt about her, looking over pictures, talking to my children about her. It hurts op, it always will do. Death isn't fair, sudden or prolonged. I didn't find counselling helpful personally, but samaritans is really useful if it gets too much and you just need to talk about it with someone. Hope you are feeling better soon.
