I need a spell to make me smaller(or a potion at that), my friend said that if I did not become 5 inches or less by next month she would not follow through with a promise to keep my secrets safe. I need help asap.
I'm sorry to say 1amb, that you cannot physically shrink you height by five inches but, if your friend really is being that awful to you why are you guys even friends in the first place? There are two things you can do. The first one I would not recommend is using some sort of memory spell. If you haven't ever casted a spell before then it could not work, or it could backfire. The second one which I would recommend, is if your friend is known for breaking promises and telling lies, try and point that out to whoever confronts you about this. Just start laughing at them when they confront you like it's rediculous. Don't laugh too hard or they will probably think it's true and if you are known for telling the truth they are more likely to believe you over her. I'd try the second option if I were you, and if it comes down to it get some practice and do a memory spell. If the next day everybody is talking about it to her and she doesn't remember then it will look like she lied to everybody.
This sounds like blackmail. If someone threatens you with the power of secrets, then take away their power. Take the courage to out the secrets yourself. What will they have left? Plus you have the bonus of no longer having to harbour secrets. Of course, nothing apart from surgery can make you change your height :)
