Re: someone is poisoning me help???

If you really, really believe that these folks are trying to poison you, then you have to take some quick action. First of all, yes, get out of there. Make your plans quietly and when you have everything ready, just do it.

You haven't said what or who these people are to you, your family, boarding house, school dorm? Why do they feed you when you come home? Are you referring to a spouse perhaps?

In any case, you ought to not just be throwing out these suspicious substances on your food and doorknobs, but instead use a piece of cloth to rub off the doorknob and save bits of the food in foil or plastic baggies. Then look in the phone book for labs where you can have this stuff tested. If indeed what you think is true, then you need to contact the police because this would be criminal activity, these folks are trying to murder you and they ought to be prosecuted. But you need to have this objectively proven, and you can only do this by getting lab tests performed.

On the other hand, there are diseases which can make you feel all the things that you are experiencing, or you have some other issues going on that make you highly suspicious of these individuals. Consider that as convinced as you are of their evil intents, it's possible that things are not as you perceive them to be.

In any case, you also need to see a doctor for some blood and specimen tests. Whatever the situation is, you can't afford to be just speculating.
Blessings to you.
