How can I manage the awkwardness when talking to people? How to cope with being socially awkward?

When I’m conversing with people I notice that I say things in a serious tone but others take it as a joke. I’m unknowingly funny. So I just stand there awkwardly trying to understand what’s so funny. One time I actually tried to laugh when the person laugh but they told me my reaction was delayed? Lol like how am I supposed to know it would be funny?
This might seem like I’m just nitpicking but I truly feel like this is one of the reason I’m single and probably will forever be.
