The 16-year-old took the party drug in June this year at a sleepover, but has now been left wheel-chair bound with brain injuries and memory problems.
Worryingly, Amy is far from alone in using ecstasy.
Statistics show the number of people aged 16-24 taking the drug has spiked by over a third in the last year, with one in 20 experimenting with it.
But the drug - which can cause anxiety, panic attacks and high blood pressure - has been linked to 577 deaths since 1996.
Just last week, teen Danielle McCallum died from a suspected overdose in Ibiza.
The 18-year-old was blieved to have taken several tablets before suffering heart failure.
Schoolgirl Amy had never tried ecstacy before.
The drug caused her organs to fail and she fell into a coma.
At one point, she was given just a few minutes to live and read her last rites by a priest but, incredibly, Amy pulled through and is now recovering at a specialist rehabilitation centre.
Tricia Thomson, 33 - who lives with Amy’s stepdad Jim, 39, in Glasgow - wants to warn other young people of the dangers of drugs.
She says: "To my knowlegde, Amy had never taken drugs before, but just one pill has left my daughter disabled.
"We don't know why this happened, it could be that her body reacted badly to the drug.
"I released a video of Amy to show how well she's doing now and help raise awareness about the dangers of drugs too.
“When I found out Amy was in a coma after taking drugs I was distraught. I prayed she’d survive and at one point I was told she had just moments to live. It was horrendous.
“Teens need to be aware of the damage escstasy can do.
"It may seem like a bit of fun, but you’re playing Russian roulette with your life.”
