Need some legal advice

My biological dad recently passed away. He didn’t have any other kids and was never married. He left a decent amount of money, but he didn’t have a will because he suddenly had a stroke and never recovered. A social worker contacted me after he was found unconscious in his apartment.

After he passed, I was told that his money would go to his siblings who are still alive. My cousin said she thinks my dad would’ve wanted me to have the money instead. However, since we aren’t legally related, the social worker suggested that I get a DNA test to prove I’m his daughter.

I don’t mind if his siblings end up getting the money, but it would really help with my hospital bills since I was diagnosed with AS. I’m not very good at dealing with things like this, so I’d really appreciate any advice. Thank you.
