So mad I could scream!!!

I went in for my test today...and after waiting there for an hour...they tell me the diagnostic person is not there to read the sonogram!  Why could they not tell me that when I first got there?!  Why did they let me sit there for an hour waiting...almost having a heartattack!!  I don't understand this at all!  Then they tell me that the first available appointment is in the 2nd week of November!  Can you believe that?!?!?!?!  I told them no, I am not waiting that long to get in.  So they looked for another available appointment and they found one for tomorrow at 11:45am at another place!  I almost had a break down there!  First they let me sit there for that long and then they tell me I wasn't going to be seen, and then they tell me I couldn't get in for another 2 weeks!  I wanted to cry!  So now I have another 24 hours before I will know anything!
Another 24 hours!!!!!!!!  I am going to go crazy!  I have already had to wait 2 weeks!  Seriously I think God is trying to teach me a lesson!  I don't know what they may be...but when I find out I will let you know!  So now I have 24 hours to think about getting this done...and then however long it takes to get the results.  I am so stressed out it is maddening!    How am I supposed to concentrate on anything?  I am supposed to be in class right now...but instead I am sitting in the library writing on here.  I know I should be in class, but I am in no mood to be around anyone, or try and act like everything is ok.  I don't know how people do this!  Go through stuff like this and put up a front...a brave front.
I feel like my heart is going to pop out of my chest! 

I feel bad, because last night my dad asked me if I wanted a blessing and I said no.  I told him whether I get a blessing or not it didn't matter it wouldn't change the results of the test!  So, I walked away from him.  I am angry...and I don't know how to handle it.  I know it's not Heavenly Father's fault...and I shouldn't be angry with Him at all.  I am sure there is a reason I am going through this...although I am not sure what it is right now.  So many unanswered questions right now...so many things unknown to me...I don't like this.  I feel like I am totally out of control!
