My biggest bit of advice I can give to you is to honour your emotions and know that they are completely valid. Personally, I find I easily get angry at myself for being angry towards others for things but it doesn't do me or others any good and it can form a vicious cycle.

We tend to take out our emotions on those closest to us as we know it'll take a lot to push them away so it can feel somewhat safe to do so. As much as it's a new reality to you, it's just as much a new reality to her. She's been faced with her own mortality and it's something we can't judge with how she reacts to it unfortunately. Make sure you're putting yourself first. Make sure you're finding time to fill your cup. I'd recommend just being open and honest and talking about how you're feeling to anyone close to you who asks. Even try and have an online chat to councellors at CanTeen. They provide help to young people who's parents have been diagnosed. Just don't internalise it, I'm glad to see you've taken step number 1 by posting in here to reach out to other who may understand! Make sure you impliment things in your day to day life that make you happy. For example, when my mother was first diagnosed I made a promise to myself to visit the beach and breathe. Rain, hail or shine. I hope this helps. x ... View more
