Germany Trip is Soaked into Water~~~

Past 2 months, I had already planned to go to Germany to attend European Spiritual Convocation, which located at Heidelberg...Therefore, I started checking the price of the flight and discussed with my friend, who study at Germany, so that I can meet her up before going to the convocation...Then I asked one of my church member about this event that who should I contact with, if I want to attend...Well, she gave me the answer after 2 weeks time and the answer was she also dint know who should I contact, so I decided to send a personal email to the person-in-chance for the event...

The person-in-chance replied my email after 3 weeks time...Well, as we know, when the departure date is getting closer, the price will increasing...Therefore, I checked again the flight ticket, and it was £70++...At this price, it still acceptable, so I need to discuss with my financial supplier, who is my parents, however, I cant contact them since I cant use my mobile call them, and they are busy attending my cousin's wedding...Until now, the price is increased to £100++...What the....Therefore, I made my decision with a cruel-hearted that I gave up this trip...I was so sad, because I was so looking forward the day I can go to Germany, but now, I have to stay at Birmingham for my holiday...Maybe this is the will of God? Anyway, I just have to accept what I have done and decided...

PS: What should I do with my Xmas holidays? Who can help me plan a trip?
