A "happy go lucky" teenager hanged himself after splitting up with his girlfriend, an inquest heard.
Louis Knowles, 18, was so down after breaking up with his girlfriend of five months he sought help from his GP.
The former Brownedge St Mary's High pupil had also dreamed of joining the Army but had to postpone signing up when he injured his leg in a bike accident.
Preston Coroners Court heard Louis was found hanged in his bedroom by window cleaner John Edwards, who had been working in Grizedale Crescent, Moor Nook, Preston, on September 1.
Mr Edwards banged on the front door to alert Louis's great-uncle, Thomas Mulaniff, who Louis was living with at the time.
Mr Mulaniff told the court he had seen Louis before he went to bed the night before and had not realised anything was wrong when he got up that morning.
He said: "Louis said to me, 'I'm going to meet my girlfriend tomorrow. We're going to have a good talk.'
"I just think it was all building up in him.
"He kept saying he was stressed and I said, 'Go to the doctor's, make an appointment.'
"He was happy go lucky usually."
Louis's mum, Janet Ealand, of Burholme Close, Moor Nook, was too upset to give evidence at the inquest.
In a written statement, she described how Louis had taken the break-up badly and had been waiting for an assessment from his doctor.
She said his actions were "totally out of character" and described him as a young man who got on well with his five sisters and "had everything to live for".
Louis left three notes in the house, saying he was sorry and "could not take it any more".
Assistant deputy coroner Howard McCann recorded a verdict of suicide.
