What does "genuinely" mean? Does it have the same meaning as "really" or "seriously?"
"Genuinely" means truthfully or honestly! It also functions as an emphasis similar to "really." "Genuinely" works well here since he's emphasising the truth of the fact, as opposed to the seriousness of something. Ex: I genuinely forgot about the meeting. = I honestly forgot about the meeting. Ex: Genuinely, I've never seen a movie as good as this one before. => extra emphasis

I don't know how to understand the meaning of "irrational fear". What's "irrational" mean here?
"Irrational" means "not rational". To explain it with other words, something that is "irrational" cannot be explained with logic or reason. An "irrational fear" means a fear that has no logical reason to exist. Ex: A lot of people have an irrational fear of spiders despite the fact that most spiders can't hurt humans. Ex: My mom is afraid that I won't eat enough when I move out, but I think she's being irrational.
