To put it in a better way, this is what we call ‘suicidial tendency’… these thoughts are so common in almost every one of us, at least for a fraction of second, during our life time… but, the actual problem is when these thoughts rule more than a second on our mind…

Why these thoughts come into our mind???

Many people experience suicidal thoughts at some time in their lives. Individuals with such thoughts may wonder if they are normal.
In otherwise healthy people, such thoughts are often brought about by a sudden, unexpected, and usually negative change in life circumstances.
Sleep deprivation that can be the result of having a very late bedtime or being unable to go to sleep is just one lifestyle issue that can increase the risk of suicidal thoughts and attempts.
Suicidal ideation may be part of many mental illnesses, including depression, bipolar disorder, schizophrenia, and drug or alcohol abuse.
Strong evidence exists that depression and many other forms of mental illness can be passed from parent to child and that a tendency toward suicidal ideation and suicide is likewise inherited.
People who have a history of previous suicide threats or attempts are at higher risk of attempting suicide in the future.
The risk of developing suicidal thoughts in reaction to medications is thought to be higher in children and teens, although still uncommon, compared to adults.
Regular or even occasional intake of drugs or any long term diseases ruling our mind or body can cause these thoughts…

How can we rule out these thoughts from our mind???

For the otherwise healthy person with no signs of depression, a psychiatric disorder, or drug or alcohol abuse, fleeting thoughts about death are usually harmless. However, any current desires to die make home care completely inappropriate.

If anyone, including the suicidal person has concerns that the person might be depressed or have other difficulties, then home care is not appropriate.

A concerned friend, partner, or other loved one should inquire directly about thoughts of suicide.
Contrary to conventional wisdom, asking about suicidal thoughts or plans does not put the idea in the person's head.
If you are concerned that someone may be depressed or suicidal, then ask in a direct and caring manner.
You might simply say, "You seem down to me, and I'm concerned. Is everything all right? Do you have any fear of being alone? Are you experiencing thoughts about death or suicide?"
