the difference between may and maybe?

the difference between may and maybe?
Can I put the world maybe in the middle of the sentence?
For example can I say ': I maybe stay at home or at school?

‘Maybe’ cannot be used in your sentence.

Are you confused with ‘maybe’ and ‘may be’?

Maybe, the compound word, is an adverb meaning “perhaps” or “possibly.”
May be is a verb phrase meaning “might be” or “could be.”
Examples:
Maybe I will go out tonight.
I may be going out tonight.

This means that in your sentence, you would need to change the verb ‘stay’ to a gerund form in order to use ‘may be’:
I may be staying at home or at school.
