Answer: A heartbreak
While a heart attack could possibly be genetic, a heartbreak is not. Any one of us could suffer from a heartbreak at any point in our lives, some more often, while others none at all.
Believe it or not, the broken heart syndrome causes the release of plenty of stress hormones (adrenaline), making the heart weaker and temporarily "stunned".
"Acute emotional stress, such as being involved in a car crash, losing a loved one, losing your job, going through a divorce, having a bad boss and experiencing natural disasters such as tsunami or earthquake, are known to be triggers in healthy adults... (Dr. Zulkeflee Muhammad, Clinical Cardiologist, NHI Malaysia)" - Read more here.
In Malaysia, when someone loses a loved one and is heartbroken, they're left to deal with the situation on their own. Some managed to wake up and move on easily, while others struggle for years before they could stand on their own, and there are some unfortunate ones who would take their own lives to end their miseries.
Family members can't do much, relatives just make a mockery of the loss (esp. if it's a divorce), colleagues lend both ears but only to give you a chance to speak to "someone" whom you badly need. Going to a psychiatrist costs money, not to mention that people's perception of you change the minute they know that you've gone to a shrink. Where is the Support Group? None... not in Malaysia. Here, you'll need to be a member of a religious community in order to be "saved".
So what happens to those who have this broken heart syndrome? We can only pray for them that they will eventually see the light, and if possible, be with them as much as we can - not just to listen, but to comfort and to guide. Leave them alone, and chances are, they will go astray.
