How to get over it & support others

[SheRaa]

My Mum died in October 2 1/2 months after being diagnosed with cancer.

I have been doing alright considering but my 6 year old is constantly crying & upset about losing Granny.

It’s so fucking hard to keep it together when you’re trying to support others - especially little ones withbl their grief.

Feel like I can’t heal the wounds as they’re constantly being ripped open.

First of all, i'm sorry for your loss.
I lost my Mum when my dc were similar age (and younger). For me, I chose, after a while, to go to a bereavement support group. It gave me 2 hours a fortnight to just focus on me - it was so valuable, and so needed.
From that, I learned (amongst many, many other things) that life won't "return to how it was", but there will come a time when you will begin to get used to "the new normal". That, in "the new normal", you will get to a stage when it is okay to laugh, and have times when you don't think about her for a bit. You will get to the stage when you can think about her and 'remember when...{insert a lovely memory, or a memory of something funny}' and you will smile or chuckle to yourself rather than cry. There will come a time when the balance of those 'happier memories' start to come more frequent than the times when you well up. You will never stop missing her, and wishing she was with you still, but the balance turns.
The time scale is different for everyone. It gets hard when everyone else seems to have 'gone back to normal' and you want to scream about this gaping hole in your life. You need to look after yourself first, or you won't do such a good job at looking after others close to you.
