lack of sleep sickness condtant stress all affect the energy in ur body. if you have less energy spare because its being used to heal you or help u function physicslly itll be harder to Use EM as less of your energy is avalible for use. Since EM is fundamental to all kinesis. you will it very hard to use any. my ESP takes a hit when im tired or sick. but stress doesnt seem to affect it much. ESP for me. so long as i can think clearly i can generally use it.
