The funeral mass of Grace Lynch heard that her death has resulted in many feelings, including pain, hurt, loss and anger.
The Dublin teenager died after being hit by a scrambler last weekend.
Hundreds of people gathered for the funeral at St Oliver Plunkett's Church in Finglas.
Grace's mother, Siobhán, said the 16-year-old was loved by many and was only starting out on life.
She told mourners that her daughter will be missed forever and that life will never be the same again.
"I love you baby," she said.

Fr Seamus Aherne said that Grace was full of life, love and kindness, adding the community will always remember the day that she died with a broken heart.
He said her grandmother described her as someone who always believed there was good in everyone.
Fr Aherne told mourners that Grace was a typical teenager, someone who took her sisters' clothes, who kept her room as a 'disaster zone', and was a music lover.
Among the songs performed at the mass was 'Amazing Grace'.
She was a friend to everyone and bubbly, Fr Aherne said.
Among the gifts offered were a school jumper, a jewellery case and a self-portrait.

The chief mourners were Grace’s mother Siobhán, father Martin, her two sisters, and her younger brother.
Earlier, the cortege paused outside her school, St Michael's, as students said goodbye to the fifth-year student - releasing balloons into the sky.
Lampposts along the route were decorated with red ribbons, said to be the teenager's favourite colour.
Many of the mourners were also wearing red ribbons.
Students formed a guard of honour leading into the church.
Members of Dublin Fire Brigade were also in attendance.
Grace died after being hit by a scrambler last weekend on Ratoath Road in Finglas.
An 18-year-old man is before the courts charged with dangerous driving causing her death.
After the mass, Grace was buried in Dardistown Cemetery.
