I care for an adult child with OCD and anxiety, so I can relate to your daily struggles supporting mum in her battle with anxiety. However, at the same time, it's hard for me to imagine how challenging it must be when the roles are reversed.
Brayden, I really want to encourage you to reach out for help and support as I'm really concerned about you. This is not something you should have to do on your own.
You can talk with a teacher, school counsellor or your GP. Or perhaps with a mate's parents or an extended member of your family. Pick someone you trust and that you are comfortable with. Does anyone come to mind?
It's ok to ask for help and certainly better than the alternative of you "losing your mind". I have help caring for my daughter. I talk with my doctor, a counsellor and friends. I could not make it through without this help and I am an adult.
I know you want to help mum. And I know you are doing your best. But somebody also needs to be looking after you.
This may sound funny as we've never met but I am really proud of you. You are obviously a very kind and loving son. And you are brave to reach out here for support.
Kind thoughts to you
