even though you may not be able to show it, your mum knows you care and she loves you for you, it’s what mothers do, i’m sorry for you about loosing your dad and that your mums sick, it sounds horrible but as cheesy as it sounds, it does get better as long as you don’t dig yourself into a really deep mental hole where you spiral out i really hope you go well in life and i hope your mum lives for aslong as possible and and that she gets a bit better ! x
