Are the tenses used correctly?

Hi. Could you tell me if the capitalized verbs in the following paragraph in the correct tenses?

You suggested that I shorten up the length of my sentences. Well, sometimes I really DIDN'T know how to do so even though I WANT to. It SEEMS to depend on the sentences but not my mind. I COULDN'T control my own sentences well.





Thanks in advance.

No reason to use past tense:
