I don’t have an answer as to how you carry on without them- but you do.
My relationship with my mum was very similar to yours, and I lost her six years ago; it was brutal. The irony of needing her more than you ever did when she’s not there is very strange.
It’s hard, it’s tough- but you are about to find out how amazingly strong you are. That doesn’t mean you’re going to be fine straight away, you will be a complete mess, and that’s how it should be; the reality of grief. When you love someone so deeply that you’re not sure where they end and you begin, grieving them is messy and raw and painful and -in parts- beautiful. It takes time.
For me, the strength was in putting one foot in front of the other and just keeping going. Six years on, the ache is manageable, I don’t cry at adverts or want to punch old ladies because they lived to an age my mum didn’t, and I can be happy. I feel as if the grief has made me more human, and more able to understand what so many people are going through every day.
I would say just concentrate on putting one foot in front of the other now. There is nothing you can do to prepare for grief, so don’t bother. You will do it and you will look back and be so proud of yourself.
Sending love to you and your mum 💜
