how can I add up the duplicate values in SQL?

I want to know the total number of tweets by the hour but it gives me duplicates.

SELECT DISTINCT datepart(hh,tweet_created) AS hours_tweeted, COUNT(tweet_text) AS total_tweets
FROM [New_years_resolutions_2020]
GROUP BY tweet_created
ORDER BY total_tweets DESC;

I want something like this

>Solution :

You can try this query to get the desired result

SELECT datepart(hh, tweet_created) AS hours_tweeted, COUNT(DISTINCT tweet_text) AS total_tweets
FROM [New_years_resolutions_2020]
GROUP BY datepart(hh, tweet_created)
ORDER BY total_tweets DESC;
