I think that giving these kids a reason to live , by making them responsible for someone, let it be a special needs child, or any other person will make them feel needed, and will be helpful for their self esteem.
I also know that juicing (using organic) fruits and veggies make people connect to Hashem. I have seen it happen and I know that when people are full of toxicity, there is no room for kedusha. Detox is very important. I have done this for someone and it worked really well.
Detox can be done by juicing and then coffee enemas, by using supplements, eating healthy food, not junk. This will reconnect a person to Hashem. There are many other ways to detox, but its too many to name. I always wanted to create a program for these kids, but have other projects I am working on, but this is a very important part that I would work with.
We cant figure out why so many kids are OTD, but we are putting too much garbage in them and them their brains dont function correctly.
