Dear friend. I only can post the same thing: don't do this.
If your parents pressure you and if there is no way to escape - you will go thru a long list of questions. Please ask here, be prepared. Give really good but wrong answers. Show you don't understand the questions. Look also thru the article again: it says, if you feel ready, you should do the dip - not because your parents want you there. So please, don't do this. I'm so sorry for you. Stay strong ans out of the water.
Hugs from germany.
