Hi Sparrow2,
Getting through the first year of firsts feels completely unreal. Even now I ask mum why she had to go? I don’t think I’m quite accepting the fact mums gone.
Empty spaces of where mum and me would go are still challenging. But I find I have to still go to these places.
I have to keep busy or I become quite low.
Yesterday, I really found it quite upsetting. Just everything was feeling heavy.
Possibly because it was late and I was tired. And when I was driving back in the dark. I seem to of come across some real inconsiderate drivers who were quite menacing. And then just not having mum to chat with. It does get quite lonely as she was always around to chat with. I really miss mum a lot. And still do.
Learning to adapt and navigate without mum, when she always around and giving me the right advice. Is hard now. I can’t just run my ideas past mum any more. 
I find I am always asking ai or google for questions and answers that I would’ve asked mum for.
Mum really was always right. She had a way, as I am sure your lovely mum did, of assessing situations and things always turned out to be just as she had said.
I definitely found I could think faster then and more confidently when mum was still with me. I’m working on this part, but for so long I was too upset most of the time to think anything good.
And not having enough support at the beginning of mums passing with no real signpost advice from anyone. Was really hard too.
Now I find things like bereavement cafes largely irrelevant and many folk just chat about their spouse loss. Not specifically with a ‘joining in element’ either.
I found specifically tailored help from the brain tumour charity could help answer more of my questions and ‘why mum had a glioblastoma?’ I still found mum’s diagnosis to passing away, 6 months, too fast and unfathomable.
Mum was so active, so ‘well’ on the outside.
When your mums birthday is here, it will feel so sad. I understand what that loss will feel like. 
With the inscription you had made on the stone is a beautiful sentiment you have had made and it will be a forever reminder of the love you still carry for your mum.
Take care. I hope you have a peaceful day tomorrow. Kindest wishes. Wuu
