Hi Obviously, I would say this since I am a psychiatrist...there are many psychaitric conditions that can cause insomnia. But before you go and see a psychiatrist, please go and see a good physician to rule out physical causes of insomnia. If there are no stresses in life and there are no environmental conditions like noise or heat in the room or light coming from outside, or you doing stimulating things like video games etc during nights or taking stimulants like tea/coffe/coke/smoking/stimualnt drugs like cocaine etc, then there is no reason why you should be having such a severe isnomnia, except that you may primary insomnia (i.e insomnia which is not secondary to any other reason) for which you may need extensive (and yes expensive as well) sleep tests. If you are able to keep yourself safer, than no problem in trying out any system of medication to see if it helps as some of allopathic sleeping medication like alprazolam (alprax). daizepam, temazepam etc are all highly addictive. But if you need quick solution so that you can be safe, given the fact that you are already having suicidal thoughts, please go first to a physician and if that does not help in few days, go for a psychiatric consultation. Please ask one of your family members to hold all medications and other dangerous thigns with which you can hurt yourself under lock and key and if necessary, if the thoughts are so severe, for them to be with you day and night so that you can be kept safe till you are ok again. This will be needed only for a short period of time, as I am sure that you will recover with two - three nights of good sleep. If suicidal thoughts persist even after that, then it would eb the time to run to see a psychiatrist. If you live alone and are not able to keep yourself safe, please consider voluntary admission to any hosp
