I was around 12 or 13 when my mother first had breast cancer and I didn't tell anyone because it wasn't mine to tell and it didn't affect me in a negative way, mentally or other. I put myself into sport as an outlet and I didn't see it as a serious thing because of my age and I was used to hospitals, doctors and illness through my Nan. She got better and gained remission.
I am 19 now and a year ago she was diagnosed with terminal secondary and I spent the summer in a different country with other family because she had already organised it and it didn't quite feel real whilst I was there. The change in her when I got home was fair but still didn't feel real. I am super close to my family. I have no idea how long she has left, I've tried to find out as sort of a way to deal with the unknown but it's difficult to bring up in such a situation. I had to make it clear that they need to tell me things; now they call me when they get results from scans, treatments, etc. But I've never been told a time period.
Since, I've found it hard. I'm living away at University and when I am home, it's usually me, Mother and brother (who has depression and spends most of his day in his room). I feel obligated to be around constantly when I am home because I don't know when she'll need me and I'm scared to lose time with her, I don't go out with friends until Mother has gone to bed unless Father is home so she has someone to be around and have a laugh with or bond with.
When I'm at University, I try to keep a sleeping schedule because when I'm awake at night (and I seem to be often at the moment), I get panic attacks because I'm so scared I won't be able to deal when she's gone and I have no idea when that could be, she might never see me grow up, see what I'll turn out to be or see all the kids in the family grow and change. It's like a fear of change. It's like I'm already grieving even though it's okay for the moment. These panic attacks can be triggered by things too; I saw a funeral in a TV show the other night and I couldn't control my thoughts. That and I don't always feel like I'm in my own body, I'm too wrapped up in my own head.
I don't feel like I can talk about this to my family because we have so many issues at home otherwise and I'm always the strong one; the one who doesn't cry, the one who helps and just hangs out, watches movies, will do literally anything for her. Talking to friends or housemates feels like a burden and I don't want to put them through seeing my like this when I'm such a positive person constantly to compensate with my feelings.
My University knows my situation and my lecturers have always said I can come to them but I don't think I could without breaking down or feeling bad for putting it on them.
I'm just not sure what to do to stop these negative thoughts and to stop the worry and fear.
