Aw c'mon, why does everyone take the pi55 when this guy posts? If he only has us to ask for advice the least we can do is try to help.
Matty, don't try to prosecute your mum; it won't do you or her any good (and she's still your mum after all). I realise she is irritating you but stay cool and ride through it. Life gets harder than this believe me so save your strength for when it really matters.
