Horrible . terrible . awfull

Dear Alan and Torsten! I have difficulties with using the following words: teriible. horrible, awfull. I don 't see the difference in the meaning and I often hesitate when I must choose( while I write letters to my friends)
Help me to manage these difficulties.

Many thanks

Hi,

All the words are very similar in meaning - check the spelling - AWFUL/TERRIBLE/HORRIBLE.
