sorry to hear your having a rough time with it, i know how you feel, i skipped phase 1 and went straight on a hardcore diet along with prescription antifungals as well as herbal ones!! and yes i was knocked for 6 for about 10 days but im not gonna let it get the better of me so carried on out of stubborness even tho i felt that i should of really been in hospital !
as for going mad/crazy thoughts dont worry about it, its normal a side effect of candida is anxiety. i suffered with anxiety/panic attacks etc very bady for about 4 years and what you describe is some of the things that were happening to me.
but as soon as ime and treatment move on all those things WILL pass and you WILL feel better. As for your son dont worry about doing anything silly or crazy because i have 2 kids and was i was suffering nothing ever happened because the subconsious instinct kicks in instead of the confused hazy consiousness when you need it too so rest assured.
hope this helps
