The first was in 2001 (as reported) and now we're in 2023, and this was just getting worse, and she just afraid he's going to go kill himself because his pains are so bad and there's nothing, she meant she has taken him to emergency room, she has taken him to the doctor's, he's taken X-rays, his body is aching, his chest just feels the pain, and he was perfectly healthy before the shot. And that's the only thing that he doesn't even take any medicine, she can't believe that there's no one out there like her son, you're making it seem like my son is the only one out in the whole world who has these pains so you're saying he's going crazy on his own, that this pain is not for real. they can't find, they can't see.
