My sister has become a total nightmare since she got a new boyfriend

DEAR DEIDRE: EVER since my sister got a new boyfriend, who is 15, she’s been a nightmare.

She’s 16, I’m 14.

We’re close and there was always a fun atmosphere in our house but these days she is either rowing with our parents or shouting at me.

Mum says the boyfriend has mental-health problems, like self-harming and talking about suicide.

I know that’s worrying, but why do we all have to suffer.

Am I a horrible person?

DEIDRE SAYS: You’re not horrible. Everyone needs to feel happy and safe at home.

But her boyfriend needs support.

Your sister is probably stressed and worried about him, and taking her fear out on the people she trusts.

Tell her about Papyrus, a service that supports young people thinking about suicide and the people who love them.

Get in touch by phone on 0800 068 4141, email pat@papyrus-uk.org or text 88247.

Your sister can get help and, more importantly, so can her boyfriend.
