My diary

Today is I began diary first day.     "Today I began my diary." or "Today is the first day that I wrote a diary."

Today is I felt very bad, because today my country is rainy.

I said "you are very hateful rain!" in my mind.

I watched a TV drama at a later time.(it is an English drama)   or   "Later, I watched a TV drama."

I ate 2 onigiri at a noon.     Generally, we spell out small numbers like 2. So in this case "I ate two onigiri at a noon."

and I went to bed at 11:30 pm.        

Do not start sentences with "And". If you want to use "and" you need to combine the two thoughts into one sentence.   "I ate two onigiri at noon, and then I went to bed.

see you! ((((((((((っ･ω･)っ buuun!

Good luck with your English studies!
