im crying

I had a hair and m/u trial scheduled for today, or should I say suppose to have had one.
I booked this trial over 2 weeks ago, I told them that I dont want an updo (they kept bringing it up) and that I want extensions and long wavy hair down. they said ok so we are booking u for 1st to talk to our extensions person and after that hair and m/u trial.
I came in last week just to make sure that I have everything and to understand how this process of extensions works. again they said at ur trial we will explain everything.
today I come in, the extension girl talked to me for 2 mins and then told me to wait so I will talk to the hair person. the hair person comes up and says well we cant do ur trial w/o the extensions
say whaaaaaaaaaaaaaat??????????
didnt I fking kept asking them about this like gazillion times???? why they wasted my fking time???? I was just stunned as she kept saying that I 1st need to buy the extension and then she will do the trial. I said that I am not going buy anything until I know what the hair will look like and I see their work. I also asked why wasnt I told that I need the extensions 1st? she said that the owner told me so - FKING LIE!!!
at this point I just got up and left w/o saying another word.

I dont understand why all of this is so hard for me!!!! I just want this whole wedding BS to be over. I am sick of it and and cant take it anymore. every single thing is like this situation. I am not enjoying myself and just want to cancel everything.

I am sitting here, typing and crying hysterically......
