No. These are some correct versions (there are others):
'I was so exhausted that I couldn't stop myself sleeping.'
'I was so exhausted that I couldn't help sleeping.'
The verb 'help' in this context means 'avoid', 'prevent', 'stop'.
The expression 'cannot help' is sometimes colloquially followed by 'but', but that is illogical, as it reverses the meaning. 'But' in that context means 'other than'. Therefore, if you say you 'cannot help but' do something, you are saying that you cannot avoid doing other than that thing. Or, in other words, that you cannot do that thing.
English is full of such interesting examples of odd usages. They are part of what makes it such a wonderful language. By all means, use 'cannot help but' to mean 'must' if you want to. You will no doubt be understood. But it's not a bad idea to think carefully about the meaning of everything that you say or write, and to be aware of whether the real meaning of what you are saying is the opposite of your intended meaning.
If you do want to keep that construction in the case of your example sentence, you would say 'I was so exhausted that I couldn't help but sleep.' You would not include the word 'myself'. 'To help myself' means something else altogether.
To start with ME, not myself.
No, the correct way to start the sentence would be "Robert and I are..." because the pronoun "I" is used as the subject of the sentence. Using "myself" in this context would be incorrect.
Yes, it is grammatically correct.
The correct sentence is: "Contact either John or me." The pronoun "myself" should not be used in this context.
even though my windscreen wiper was on i still couldnt see ahead of myself due to the heavy rain.
The correct sentence should be: Brian and I will be attending a seminar.
Yes, "Please submit the report to Johanna or myself" is correct grammar. The use of "myself" as a reflexive pronoun in this sentence is appropriate because it refers back to the subject, "I."
No, the sentence is not proper English. It should be "We are talking to ourselves."
yes
"I confirm John and myself as participants" is correct. "Myself" is one of the "reflexive" pronouns, which should be used whenever an element of the predicate of a sentence represents the same person as an element of the subject of the same sentence. The easiest way to remember is: If you say the sentence again, but leave out "John", you would then say "I confirm myself as a participant." You wouldn't say "I confirm me as a participant."
no. you should only use "myself" when previously in the sentence you have used the word "I". proper grammar is "me and my directing partner". using myself would be correct if the sentence were, for instance, "I went, myself, along with my directing partner" although frankly, why not just say "i went with my directing partner" anyway, you get the point I'm sure.
It is important to note that there is a grammatical error in your sentence. It should read: "It is important to note that I."
