What is the word to indicate that a thought has been repeatedly occurring to me since 2 days? [closed]

The word recurring can be used both for positive and negative things:

This thought has been recurring to me for the past 2 days.

Lexico provides a positive/neutral and a negative usage:

1 Occurring again periodically or repeatedly.
‘gratitude is a recurring theme in the book’

1.1 (of a thought, image, or memory) repeatedly coming back to a person's mind.
‘they are haunted by a recurring image of their daughter on the night she died’

but I'm pretty sure thoughts can be positively recurring as well.

Persisting.

‘This thought has been persisting for the last two days’ (note - you cannot say ‘since last 2 days’, that’s not correct).
