When you have a word with 2 or 3 syllables, you should look for rhyming words with a similar number of syllables. For example, led would rhyme with bed. But even though "threatened" ends with the "-ed" sound, it would not rhyme well with the words bed or led.
However, many longer words ending with "-ed" would work well as rhyming words.
Some words that work well are:
Forgetting
Regretting
Words like that. Hopefully those are okay.
heaven, seven, set in
The feeling "dread" rhymes with "dead." It describes a strong feeling of fear or anxiety about something unpleasant or threatening that may happen.
