My sympathy goes out to you and your daughter, Alan.
I have lived (in a supportive role) with depression for many years and from my own personal experience(s) every single situation is quite unique from the rest.
Sadly, the pharmaceutical industry have a multi-trillion dollar incentive to mislead the medical fraternity, and have been extremely successful in returning lucrative dividends demanded by its stakeholders over many decades now. I remain confident that real change is just around the corner now.
Unfortunately, much to the ignorance of our conformed society the mind boggling profits being splashed out among these greedy souls, comes at a much higher price being paid by people like your son in law, and the support network around him, like your good self, and your daughter.
Unlike your son in law I also know many people who have been diagnosed with this debilitating illness, and prescribed highly toxic mind altering drugs from their local GP's who I would subscribe have very little to no educated opinion on this topic, and imo are certainly in no way or form qualified to prescribe such dangerous drugs to any patient.
My former partner of many years, and the love of my life was prescribed an excessive dose of Zoloft from the age of 7 years old - Accordingly, this GP has since lost his license for medical malpractice, but unfortunately this is no isolated incident, and a large majority of practising GP's today continue handing out these highly toxic chemicals like they are some kind of candy bars.
In my view, which you may find is also backed by a significant amount of clinical evidence, your son in laws attempt at suicide may indeed be a result of actually consuming the medication rather than his failure to take it at the regular recommended intervals and dosage levels prescribed by his doctor.
Of course, if there are any 'qualified medical practitioners' reading this post they will undoubtedly strongly oppose this notion, however unless any of them have truly experienced this debilitating illness first hand, their opinions which have been formed on the basis of outdated college text books and smooth pharmaceutical sales representatives are as meaningful to me as a automotive mechanic desperate to remain solvent.
"For the past few days, he keep saying that (1)he did not do it, someone else was in his body and take control of him ( I am not certain if he is telling the truth?)"
Again, from my own experience in a supporting role, many persons who truly suffer from this 'invisible-to-the-rest-of-the-world' illness may experience some form of 'voices' in their head which can be extremely controlling and persuasive in a negative form, often delivering a constant message of unworthiness, hence the tendancy towards suicidal thoughts or fantasies.
I once believed that suicide was a truly selfish act carried out by any human being, however my own experiences with love ones who truly do suffer from depression have opened my eyes to a very different world from the one so called 'normal' functioning people like you and I live in.
The last thing in the world many people suffering from depression wish for is sympathy. Treat your son in law with respect and dignity and remind him that he is not to blame for his illness. People suffering from depression are certainly not weak, nor are they a failure, and I believe it's vitally important to remind them that you think no less of them for having an illness which they have very little control over. Always encourage conversation, be very understanding, and try to be a very good listener without making judgement.
Also from my own experiences, where a loved ones serious episodes of depression may appear to only last for hours or a couple of days at a time to you or I, it can be an extremely exhausting experience which will often feel like a 'lifetime' for the sufferer every single time, so I believe it is also equally important to constantly give the person hope for recovery, and I truly do wish for yourself, your daughter, your son in law, and all sufferers, and the supporting networks around them, that we will be provided with a real solution in the very near future.
The following quote was firmly etched in my mind when I was looking for some answers myself some time ago...
"Depression is a very selfish disease, it cares not who it destroys"
Good luck Alan. I wish you all the very best mate.
