It's really shocking and it's quite sad to know that. I am base in Singapore and I know that the education system here also causing kids a lot of stress and the parents here also very "kiasu" (afraid of failure). I don't see kids enjoy learning and treat gaining knowledge as a joy for self-improvement. I try to make my kids have fun while learning as much as possible as I know kids or human learn best when they enjoy it. Homeschooling need a lot of effort from the parents but I think it will suite the kids best as they learn in their own pace. The down side of homeschooling is that your kids will have less time socialize. Try to bring he/she out as much as possible to gain some socializing skill
All the best to you and your family
