I believe you have either :

Suicidal ideation, or

Suicidal Obsessive Compulsive Disorder (SOCD)


You should see a psychiatrist, or psychologist.. The GP who simply told you
not to ''dwell on it'' is naive and knows little about the complex psychology of suicide.

Preferable see one who is trained in hypnosis. Dr Cheah Wing Yin in Sunway
Medical Center is one.


Suicidal ideation.

People with OCD are at high risk of suicide.

Some drugs, or sudden withdrawal from, particularly the SSRIs, can
also trigger off spontaneous suicide or suicidal thoughts.

Have you been on any of these drugs , such as Prozac, Zoloft or Effexor ?

Effexor, being an SNRI and blocks both serotonin and noradrenaline, is
in particular associated with a high risk of suicide on sudden withdrawal.
