He wrote: ‘I just read the news about Mr Philip Seymour Hoffman against the advise of others; I had to write this open letter. I can’t stay quiet anymore about this… I am an alcoholic and a drug addict (sic).’
The actor felt compelled to write about his addiction following the news that Oscar winning actor Philip had been found dead in his home after a suspected drug overdose.
‘I even question whether or not I should publish this, as I type out these words but if these words can encourage someone to hold on to their life… to keep from ever using, or to find the strength to stop; then it’s more important that these words are shared.’
Shawn then went on to condemn drug use.
‘Whether you are the occasional user, or someone that uses every day. Every moment spent using drugs (alcohol included) is a moment stolen from your life. A memory you will only recall with vague reflection – through fogged glass.’
‘I am an addict. And I’ve never been more proud, saying it. Because when I think about where I’ve been, and where I am now…’
The 27-year-old actor wrote that he is proud that he has managed to fight his demons.
‘I am proud of the man who has addressed and admitted to himself, what was once a clouded denial. Self-pride and love are two things I’ve never had for myself, until recently.’
He continued: ‘I hold them closely, now, by my own humbled awareness. And I wouldn’t trade that in for any pill, line, or drink - on any day. I could go on, but I’ll leave it here, for now.’
The actor starred as Andrew Van De Kamp in the hugely successful Desperate Housewives. The show ended in 2012 and he has since won a role in an American TV series and starred in a TV movie.
