The Daily Mail reports that Jack Wall died from multiple injuries after he was hit by the Portsmouth to London Waterloo service at Liphook railway station, Hampshire, last November.
An inquest heard that the 18-year-old, who suffered from attention deficit hyperactivity disorder (ADHD) and was described as 'hyper-sensitive', had fallen out with his mother, Tracy, after he failed to complete his chores, including picking up her medication from the chemist.
Tracy, who was divorced from Jack's father, told the hearing that she had told her son to sleep at a friend's house that night as a punishment.
"I decided Jack could do without some creature comforts for one night and he could sleep on someone else's sofa for the night," she said.
"We had words but we didn't shout. I said 'Get out, get out, you are just like him (his father)'. I went downstairs, Jack came down and said 'Say goodbye to your son'.
"I said 'Bye Jack' and Jack left the house and that was the last I saw of him."
She added: "Jack was a very loving person. I would describe our relationship as being a married couple without being a married couple. Jack was my world. Jack was a very loving, sensitive young man and he did get easily upset."
The inquest heard that Jack sent a message to his friend saying he was 'broken' after a 'decade of psychological abuse' by his mother
Friend Luke Mees, told the inquest he received a delayed message from Jack speaking of troubles he had been having with his mother and saying he intended to take his own life.
The message said: "It took me a long time to finally make this decision. I don't even know where to start!!! Let's start with saying I have suffered almost a decade of psychological abuse from my mum and I'm broken!!
"Years of being told 'You're just like your father!/You're a nobody!/I wish I had a better son!'
"I don't want to continue living after all that has happened in my life since coming to England. Watching your mum physically hurt herself and blaming it on you!
"That's what destroyed me!! I chose to entrust you with this message because I know you're the one who has chosen to stick by me through all my problems and I'm so sorry!"
However, Jack's grandmother Eileen McGrath said: "Jack never said anything to me about having problems at home. I can't believe it's true, they were so close and loving all the time."
The inquest jury of six women and two men returned a verdict of suicide.
North Hampshire Coroner Andrew Bradley said: "Whether it (the message) is true or not perhaps is a reflection of what Jack was feeling at that time.
"One doesn't have to distinguish whether it was right or wrong. For him, it was real at the time."
