I'm facing homelessness and I genuinely don't know what to do.

So, I live in my grandparents house and recently he had a medical emergency so he had to end up in the hospital. My aunt, who was given power of attorney, is kicking me my dad and a friend of mine who came to live with us because of a similar situation out so she can sell our house to pay for medical bills, but for every reason under the sun and more I feel like she's lying and just trying to steal the money through her POA. I'm kind of up against the wall rn, as none of us are currently employed or have any assets to speak of. I graduated from highschool 2 years ago, and have been trying to look for a job for 1 of those years and it hasn't been going well, as I don't really have any experience to speak of outside of First Aid 2 training I recently got due to a loan from a friend. Would really appreciate any kind of advice whatsoever because I have no idea what to do.
