I personally think it's always better to tell people how you feel rather than keep it inside. Because if you don't tell anyone, and you don't seek help, things can get much worse until you are at a point where you need to be sectioned or you commit suicide.
I agree with this. Even if you dont feel able to talk toy our mum, maybe a phone line or someone else like a tacher, social worker or someone who used to be involved in your care.
