The truth is bitter.
Note: There is no mistake in the phonetics for the third word. When the letter ‘f’ is lenited or aspirated (séimhiú), the result is that the lenited ‘f'(written as in gaelic font and as ‘fh’ in roman font) becomes silent. This is clear when you listen to the audio file for this seanfhocal.
Note also the phonetics of the fourth and final word. The phonetic spelling added a neutral vowel after the “r” and before the “bh” in searbh. So the third word dropped a consonant sound while the fourth word added a vowel sound.
