Harry Potter didn't keep a diary, that we know of. If he did he would probably have wrote about his life and his feelings.
Does Harry Potter have a diary? I have never heard about that.
Harry Potter doesn't have a diary. In Harry Potter and the Chamber of Secrets he found the diary that belonged to Tom Riddle (a.k.a Lord Voldemort). He found it in Moaning Myrtle's bathroom where Ginny Weasley had thrown it away.

Harry Potter
The diary
The only horcrux Harry Potter destroys himself is Riddle's Diary. He destroys it with a basilisk fang.
In Harry Potter and the Chamber of Secrets. Tom Riddle's diary.
There is Harry Potter and the Deathly Hallows which is the seventh book starring Harry Potter but now there is Harry Potter and the Cursed Child which is a playscript and is starring Harry Potter's third son, Albus.
No, but the diary Horcrux, was destroyed.
You might start by reading the book. Then, try to imagine what Harry would write in such a diary - and just start writing. The idea is to put the main ideas of the story, and to put it in a format appropriate for a diary.
You don't interact with the diary in this chapter.
The Harry Potter book with the memories of Tom Riddle in it is The Chamber of Secrets. The diary of Tom Riddle became alive in that book and he was who Harry had to fight.
