Hello
Thank you for posting your query at DoctorSpring.com
I have gone through your question in detail and I can understand what you are going through.
From what you have stated it appears that you could be having an OCD. OCD is a very common illness and effects many.
There may be a rarest of the rare chance of something that bizzare to happen. And even practically thinking, you also know that the thought are very unrealistically. All you need is a proper control of the thoughts. It can be mild and some times unrecognizable and sometimes it can be severe. You certainly need to be treated for OCD. Although there are plenty of options available like clonil, fluoxetine, escitalopram, fluvoxamine, sertraline etc my best option for my patients is fluoxetine in higher dosages.
Also there is an option of cognitive behavioural therapy. This therapy is taken by either a psychologist or a psychiatrist in which the therapist identifies impaired cognitions (Thoughts) and try to correct them. They are 15-20 min weekly session and there should be around 8-10 sessions to help you with your illness.
Hope I am able to answer your concerns.
If you have any further query, do let me know.
Regards.

Hello.

If you rule out the option of posions, then there is no real food material ( or a food borne disease) that can lead to a fatal body effect.
In my 14 years old patientof association with medical sciences in the developing countries where infectious disease abound, I have never witnessed such an event.
I hope this will rest your concerns to some extent.
However I would still request you to seek proper treatment for OCD as that will reduce your distress a lot. Your current treatment seems to be not working very well.
Let me know if I can assist you any further.
Thanks.
