I just want a yes no clear direct answer, it's that so hard ?

Take notice to color bold underline text.

My mother is in a non-japanese avocational music drama group. Part of their performance will require yukata.
She asked if I can lend her my yukata. And we talked about may be I would helping out, because Yukata is a japanese clothing that require certain skill/method to wear.
I said if you need me sure, I will go. I am either like or dislike to help out. And I am either want or not wanted to help out. Coz I don't want being mistaken that I disire to get involve and help out, when in the case people don't need me.

I said I will need to be notify not at the last minute, coz I would like to practice. Coz performance is live and thus there’s time limit of everything including wearing the yukata.

So I wait and wait, but no answer of whether they need my help or not. And later,I found out that teacher is still deciding if she want me to help, coz she worry I would have mental issue during the show.
I found out (unintentionally ) from my mother phone conversation with her friend, near the window, and my mother is always loud.
I understand the teacher’s worry, (I am not happy) but I can understand and I am not upset about it. It’s her show, it’s important to her.

What I am upset is that the teacher procrastinates in deciding whether she want me to help or not. I don’t like people dragging on me, dragging on my time. Okay, I am upset she procrastinate, but I can understand she feel un-easy, (procrastinate) and holding on in making the decision.

I said it’s her show, not mine. I said call me the next day to tell me the answer (yes/no). If she don’t call me by the next day afternoon, I treat the answer as no.

***additional*** I said to the teacher if she don’t need me to help, she would need to borrow the yukata from someone else instead. I said I don’t trust other people in giving them my yukata but no within my sight. And she told me actually it was her yukata and that she gave it another lady. And the lady gave it to me instead. I said in theory it’s mine now. But if she still insist it’s belongs to her, she can also call me the next day before afternoon and asking it back. I would give it back to her.******

I just want a yes no clear direct answer, it's that so hard ? I am very frustrate she will not give me an clear, direct, definite answer.

(addition) The above has been a short while, I thought I am okay already, but I am not, I still feel extremely depress about it.

(sorry I cannot edit anymore, so the only option it's to write at the reply)

I think maybe they can find other yukata for performance? Or does teacher want her yukata back? Is it very expensive? Why was it given away? These are things I would wonder about.
