Preposition "during"

[vlkn]

During my life/ During my life time, I have always been frightened to go to high places.

I was too afraid and I screamed.

Are the underlined parts correct in these two sentences?

Thank you so much in advance!

With the first, there is no need to mention your lifetime at all. If you say "I have always been afraid of heights", it's clear from the word "always" that you mean your whole life.

Thanx Thanks a lot my friend.

I was too afraid and I screamed. Is it correct? Can you reply to this (no comma required here) too, please?

You were too afraid for what? Too afraid to do what? If you use "too", you need to add more information. You can say "I was afraid/very afraid/terribly afraid and I screamed".

Please don't use textspeak/chatlist on the forum (use "thanks", not "thanx").
