people,have_harassed_me (Some words not found in UHB: song_of of,the_ascents often_of people,have_harassed_me since,youth(s)_of,my say now Yisrael )

The pronoun me here signals that from here through verse 4, people of Israel are speaking together as though they are the nation of Israel. See the discussion in the introduction to this psalm to decide whether your translation will use the plural pronoun forms or keep the singular. Alternate translation: [they have afflicted us from our youth]

The pronoun they does not refer to a specific group of people. It refers generally to the enemies of Israel throughout its history. If it would be helpful to your readers, you could indicate that more clearly. Alternate translation: [my enemies have afflicted me]
