Wow, that's a lot to deal with! Wish you and your family (especially your mum) the strengh and courage to conquer this. Hope you also find a lot of help and support from your friends outside the board.
Seems like I keep getting socks full of shit thrown at me by life
Tonje,
I am so sorry to read that your family is experiencing even more trouble. Your sock description is very fitting! My life was like that a few years ago. We were having about every trouble you could possibly imagine in our family so I can really relate to the feeling of "isn't it enough already??"
Be there for your mom but don't forget to take care of yourself as well. Don't bottle in your emotions and just try and stay united with your family as much as possible. I truly hope your mom and brother get through their illnesses healthier and stronger.
And I definitely relate to listening to Travis to help you through the hard times!
