Do you accept now that your kids might have been infected through the placenta? Its kind of a moot point as you would probably have infected them later on anyway, long before you knew you were infected yourself.
Your view, which is not uncommon, seems to be that eventually you are going to find a doctor that will be able to just 'fix' you - this may well be the case for a lot of illnesses (perhaps) but seldom applies to parasites. The way you have clearly been let down by doctors so many times in the past, its a wonder you retain so much faith in them.
You need to take the initiative and be proactive in finding solutions yourself.
BTW you never really explained exactly why it is you're with your mother and away from your kids.
