He said: “My whole life has led me to this, really. My mother had dementia, so I wasn’t right, mentally.
“All that was instilled in me, so I was extremely lonely, extremely withdrawn, very inhibited physically – scared to go out, scared of being seen, all the time scared, hugely shy.”
He told the programme that aged 15, he fell in love with a boy and said it was “unbearable” and that he “didn’t want to be gay.”
Under Belgium’s laws, anyone who wants to be euthanised must demonstrate they have “constant and unbearable physical or mental suffering.”
Sebastien is now undergoing medical assessments to see whether his wish to die is in line with the law before three doctors would have to agree euthanasia is the correct option.
Sebastien told the BBC: “I have always thought about death. Looking back on my earliest memories, it’s always been in my thoughts.
“It’s a permanent suffering, like being a prisoner in my own body.”
