Can you guys help me understand how to get started with finding primary sources?

I’ve always kind of known that primary sources are important but whenever I go to read anything I end up reading a lot of basically Twitter or Chambers or blog posts that are written by people who claim to be experts but in the end I don’t know if they really know what they’re talking about.<br>I’ve always been interested in the past but it seems like nothing is really trustworthy and that bothers me. I’ve kind of just given up and figured I can never really know anything. But then I saw my friend post about how much she loves reading primary sources about history and culture. I want to do that too.<br>What I don’t understand is where to look and what’s trustworthy. Are there any general places I should know about that are trustworthy to look at? It seems like a lot of the sources I see are held behind paywalls and require degrees and educational experience to access.<br>I’m not sure how to find things I’m interested in or where to start looking for historical events or anything.
