Hello everyone, (this is my first post so please bare with me x)

So very long story short, my mum has grade 4 glioblastoma. I already know what I need to know about this so I don’t want a reminder :( but I’m honestly not sure whether I’m coming or going at the moment. I’m at uni doing a masters which I worked so hard to get on to, but I’ve just lost all interest. Sometimes I feel completely fine, then other times (like today) I feel like I can’t even cry because it doesn’t express how sad I am. She’s my best friend in the whole world. I have to try and carry on as normal as mum said that’s all she wants from me. Is there a right way to cope? :(
