I'm getting desperate.

You use contractions when you are writing down what someone says, or when you are writing in a conversational style, for example in letters to friends.\The contracted forms of `be' are used when `be' is a main verb as well as when it is an auxiliary. The contracted forms of `have' are not usually used when `have' is a main verb.\The following table shows contractions of personal pronouns and `be', `have', `will', `shall', and `would'.\◊ WARNINGYou cannot use any of the above contractions at the end of a clause. You must use the full form instead. For example, you say `I said I would', not `I said I'd'.\◊ negative contractionsThe following table shows contractions of `be', `do', `have', modals, and semi-modals with `not'.\◊ WARNINGThere is no contracted form of `am not' in standard English. In conversation and informal writing, `I'm not' is used. However, `aren't I?' is used in questions and question tags.Aren't I brave?
\I'm right, aren't I?
In standard English, a pronoun followed by a negative contraction of a modal or `have' is more commonly used than a contraction followed by `not'. For example, `I won't', `I wouldn't', and `I haven't' are more common than `I'll not', `I'd not', and `I've not'.\However, in the case of `be', both types of contraction are equally common. For example, `you're not' and `he's not' are used as commonly as `you aren't' and `he isn't'.You aren't responsible.
\You're not responsible.
◊ modals and 'have'The auxiliary `have' is not usually pronounced in full after `could', `might', `must', `should', and `would'. The contractions `could've', `might've', `must've', `should've', and `would've' are occasionally used in writing when reporting a conversation.I must've fallen asleep.
\You should've come to see us.
