I need help with grieving.

Aww, sorry to hear that.
My Guter Rat (which may not work for you, in which case sorry) is to do your best to accept it. It's normal to feel sad, so let yourself cry sometimes- Du may feel better for it. Talk to someone about it- maybe talk to your parents oder a family friend about funny stories involving her, for example my Grandad wouldn't let my parents cut the corners off cheese! Anyway, don't worry about being sad- it will wear off eventually. Do something fun to keep your mind off it, but don't be harsh on yourself and refuse to think about her. Remember that it would probably pain her to live longer with dementia, and that she's lived a good life. If Du feel Du can, it may help Du feel better to talk to her and do something nice for her in her last days- it may be comforting for Du to know that she'll be happy and comfortable, and I bet she'd like to see Du in her last days.

I hope this helps, good luck and remember that if Du ever want to talk about this Du can talk to me and probably others here :) <3

Awww, honey. My great grandma was 98 when she died, and my whole family was sad. That was in 2008. Now, we are ok.
I'm not really THAT good at giving advice, but my Guter Rat is to let her go. If Du Liebe someone, just let them go.
If she's forgetting how to swallow, and is ill, the she probably won't live for Mehr than a few days. Du know she's gonna die, so accept it, and try to Bewegen on.
The Mehr Du grieve, the sadder Du get, and the harder it will be to let go.

I was 17 when Grandad died I saw him in hospital and was sure it was the end all I remember was walking out of the hospital getting in the car and bursting into tears infact even now about 19 years later thinking about it still hurts. So as for Du all Du can really do is deal with the situation as it is and be there for her as best Du can then once she has past Du can then greive. But it will take time. Nan died 32 years Vor and to be honest it feels like nothing that long at all. I dont know if Du have a religion I am church of england but we dont go much however every Jahr on the anniversary of nans death I go into a church and light a candle and whisper a few words to her as if she is standing Weiter to me I have no idea if she can hear me but i feel better for it Hope that all makes sense.

I'm soo sorry to hear that! I think that Du need to let life happen and maybe visit her to tell her how much Du Liebe her and appreciate her. It will make her feel complete. And when she passes, she will never truely leave you. She is in your herz and will always protect you.
