His pain hurts

so I've been dating this guy for a few months. When we got together I knew about his anxiety and I knew it was bad, but I also knew I could handle it. However recently his parents have been causing him a lot of stress and panic. He feels like he is worthless and a failure. He is still at the point where he needs their help to become fully independent and they refuse because they have given up. He is 24 and has serious crippling anxiety, the kind that causes him physical pain on a daily basis. he can't get into collage because his parents home schooled him through highschool without an online program (their idea of that was toss him some textbooks and expected he retain the information). In other words they are fueling the fire. today he came to me and said that he doesn't see a point in trying. he started crying and my heart crumpled. I wand to protect him and see him happy all the time but I don't have the power to help with everything he needs. What should I do?
