How tf do you make friends here

I’ve been living here for 2 years. Haven’t made the first friend. I’ve got my work colleagues who are mostly in their late 40s and up. I wouldn’t consider them friends but really good acquaintances.

I’m technically in southern Indiana. I’m building a house so paying to join anything more than a planet fitness has been out of the question. People here seem a little guarded and not the friendliest. Of course im an introvert so naturally I assume the whole area may be lol.

I’m open minded more on the liberal side. I like death metal. Use to do BJJ. I workout almost daily Huge DIYer Any suggestions?
