Idk what to say.

Hello! I suck at talking apparently, I stutter I mumble I don’t know when to laugh or when somthing is funny. I always don’t know when to smiles. I don’t know the difference between a happy, sad, serious, joke, conversation. I’m literally so awkward. I hate talking to people know help me please. And for any of you adhd folk, how do I get an assignment that has been late for already 2 weeks but I keep procrastinating, turned in? :/
