Father recently passed - found out he was in a lot of debt. Do I have to sell his stuff?

yo yo people. My (19F) dad passed away not too long ago, and he left me his possessions. my grandma has talked about him having a lot of debt and since he was renting our house im not sure whats gonna happen. I’m kinda panicking because I’ve read different things and chat gpt gives different answers every time I ask! Some of the stuff he left is just like nerdy comic stuff and some equipment etc. not crazy but it means a lot to do. Do I need to sell his stuff? do I keep it quiet? what exactly is right about inheriting debt. im scared to ask lawyers etc because I feel like the moment its brought up - I might be fucked. We dont come from money (clearly) and im struggling as it is. He always said he was saving for me to go to college but clearly that didnt happen. I'm honestly so anxious. I have been having panic attacks every day which has never happened before. I dont know what to do or who to speak to. My grandma is not really someone who I can ask about this stuff (they didnt have a great relationship and I only see her like once a year. fyi my parents divorced when I was 5 and she now lives in a different country with a whole new family. I do get on well with her but yeh...I dunno. any advice please Im really struggling.
