You get used to sadness, growing up in the mountains, I guess.

The line suggests a hard-earned emotional resilience shaped by place and upbringing. “The mountains” evokes rural isolation, poverty, and limited options—conditions that can normalize grief, loss, and disappointment as part of daily life. The phrase “you get used to” implies not that sadness disappears, but that one learns to carry it, folding it into adulthood as a kind of stoic habit. The casual tag “I guess” adds a note of understatement and self-protective distance, as if the speaker is reluctant to dramatize pain. Read in the context of Lynn’s public persona, it aligns with her plainspoken storytelling about hardship and endurance.
