I understand what you are going through, I am going through something similar but also quite different, I have been out there working for probably more years you have been alive but I just cannot do it anymore. With you it is your parents, me my daughters, but basically it is the same...
Why dont you try babysteps for a while, maybe a part-time job or volunteer work just to get you started???
Again, I understand perfectly what your are experiencing and I hope you will get through this.
Do you have a T you could share with, who could help you with this?
Take good care of yourself

One day at a time
