I should probably begin by saying I'm 16 years old and my mothers just 49. We found out around a month ago that my mother has incurable secondary breast cancer, and since then I seriously don't know how to cope. My parents have told me that it's going to be fought for just a year or two, but I've seen reports online saying it can kill some in months. The mood in my house has, understandingly, been very depressing and low, and sometimes I find it awkward to talk openely. My parents have been encouraging me to speak about how I feel to them and not keep anything bottled up, but they're so upset already I don't want to make it any worse for them! I only have one or two friends who I can talk to, but I don't want to burden them, and I can't bring it up in everyday conversation because it's too emotional -- my other friends don't seem to care at all and have been routinely leaving me out of group activities. I just feel overwhelmed with fear and sadness every time I see my mother in pain, anxiety for my father (who's always been /incredibly/ close to my mother -- they haven't had a proper argument in years), and so stressed for my GCSE exams this summer, which I need to do amazing in to achieve my target grades. I really don't know how to open up without sounding selfish and making anyone I know feel even worse/awkward, but I know how bad bottling things up can be.
Any support would be great, thank you
