i need advice for not making people be uncomfortable around me

so basically, i think i might loose a friendship from someone i care about and don't wanna lose because i make them feel uncomfortable

i know that i make them feel uncomfortable, and thats the weird part. whenever i know i just said something that makes them uncomfortable, i apologize over and over again but i know that they think that I'm just kidding about it and don't really take my apology for being weird and making them uncomfortable. i don't really properly know how to stop since the words really just slip out of my mouth. it's mostly the things i say, honestly. i really want to change, but they'll just don't like me either way. in general, i really just need advice on how to stop making people feel uncomfortable and how to adapt to stop making people like my friends feel uncomfortable when they are around me
