There is a section on the Form I-797C notice for the AOS interview , toward the bottom of the page. The title of the section is "YOU MUST APPEAR FOR THIS INTERVIEW." In that section USCIS describes what they consider appropriate excuses for non-attendance, i.e., your illness, or a close relative's hospitalization.They then give you a phone number to call to attempt to reschedule. If you want to try that route, I would suggest that you call them and explain your situation, AND I would also suggest that you write a letter to your Local Field Office (LFO) (the address should be printed at the bottom of the page) expressing the same information.
 
There are too many postings on these fora, where people claimed that they called to reschedule, USCIS claims that they never got a call. Then the folks didn't go the their prearranged scheduled appointment time, USCIS then claim that the "no show" indicates that they abandoned their case...end of story.  I doubt that is the way that you want your immigration journey to end.
 
When people start their immigration journey into the processes associated with these monstrous government bureaucracies, Department of Homeland Security (DHS) and their associated agencies USCIS, ICE, and CBP, they have to realize that they have given control of their lives to these government bureaucracies until citizenship, or another endpoint, is completed. Keep in mind,  it is their ball game, their ball field, their ball, and their rules, not yours.  Due to the size of bureaucracies, they have little to no regard to your schedule or agenda, they are calling the shots. The scheduling minions at the ASC in Alexandria, VA are very likely inundated with nationwide rescheduling requests, and so as a consequence, you get what they can give you. And if you can get a rescheduled appointment, you may not like their alternative appointment, either. There are many of us that understand your frustration with the system, but again it is their system, not yours. Believe me when I say, that your posting is just preaching to the choir, there are a lot of us in the choir loft.
 
You will likely not get very far into the LFO building without a valid appointment notice. Personally, I wouldn't even try that, you may end up in a worse situation than your current one, i.e., wearing a set of stainless steel bracelets. BTW, is is estimated that there are over a million cases awaiting adjudication in the immigration judicial system. Do you want to be placed into that queue?  Don't lose sight of your original goal when you started this process. 👍  Go to the appointment and be done with it, or risk the consequences of dealing with ICE agents and the immigration judicial system.
 
Good luck on your immigration journey.

i got my answer thru USCIS just in case in the future someone wants to *ASK* similar question.
Q. What publicly funded benefits may not be considered for public charge purposes?
A. Non-cash benefits (other than institutionalization for long-term care) are generally not taken into account for purposes of a public charge determination.
Special-purpose cash assistance is also generally not taken into account for purposes of public charge determination.
Non-cash or special-purpose cash benefits are generally supplemental in nature and do not make a person primarily dependent on the government for subsistence. Therefore, past, current, or future receipt of these benefits do not impact a public charge determination. Non-cash or special purpose cash benefits that are not considered for public charge purposes include:
*Medicaid and other health insurance and health services (including public assistance for immunizations and for testing and treatment of symptoms of communicable diseases; use of health clinics, short-term rehabilitation services, and emergency medical services) other than support for long-term institutional care
*Children's Health Insurance Program (CHIP)
*Nutrition programs, including Food Stamps, the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), the National School Lunch and School Breakfast Program, and other supplementary and emergency food assistance programs
*Housing benefits
*Child care services
*Energy assistance, such as the Low Income Home Energy Assistance Program (LIHEAP)
*Emergency disaster relief
*Foster care and adoption assistance
*Educational assistance (such as attending public school), including benefits under the
*Head Start Act and aid for elementary, secondary, or higher education
Job training programs
*In-kind, community-based programs, services, or assistance (such as soup kitchens, crisis counseling and intervention, and short-term shelter)
State and local programs that are similar to the federal programs listed above are also generally not considered for public charge purposes. Please be aware that states may adopt different names for the same or similar publicly funded programs. It is the underlying nature of the program, not the name adopted in a particular state, which determines whether or not it should be considered for public charge purposes. In California, for example, Medicaid is called "Medi-Cal" and CHIP is called "Healthy Families." These benefits are not considered for public charge purposes.
In addition, and consistent with existing practice, cash payments that have been earned, such as Title II Social Security benefits, government pensions, and veterans' benefits, among other forms of earned benefits, do not support a public charge determination. Unemployment compensation is also not considered for public charge purposes.
