In just a few lines, the speaker admits to a painful loop of thinking. They wonder how anyone could love them, given their "flaws / And quirks," and then follow that thought to a harder one: if they can't love themselves, how could they let someone else do it? The question isn't really about other people. It's about the speaker's own opinion of themselves, which seems to be the thing standing in the way.
The tone is quiet and honest, a bit like a private thought said out loud. The short, plain lines and the lack of fancy imagery make it feel unguarded, as if the speaker isn't performing for anyone. The word "even" in the last two lines adds a weary, almost defeated note. The mood is vulnerable and sad, but there's also a kind of self-awareness here. Seeing the problem clearly is not the same as solving it, yet the speaker has at least put it into words, and that's often where change begins.
