Without going into how much I feel for you in this desperate situation - which almost goes without saying - I'll just reiterate an earlier message I gave you - that its likely that your kids are infected (it could also just be they really miss their beloved mom) but this doesn't mean for a moment that its in any way your fault. Given that you had worms for a long time before you knew, its surely the case that they would have been infected just in the course of daily activities, and not via the water bottle.

The other critical thing to consider is that just because your daughter had a crawling sensation in her foot does not in any way mean she has the kind of chronic dissemination issue that you are dealing with. Remember its not unusual at all for them to leave the intestines in small numbers - and there's no reason to think that she has the leaky gut issues that lead to your situation. Are your kids having any treatment at all? Its more than likely that if you can get them on one of ICU's protocols then they will be able to get back to full health relatively fast.
