Will my dream ever come true?

I constantly think about the same thing, music! everyday when I wake up, or before I go to bed its all I think about. I am 16 soon to be 17, write my own songs and have been doing so for the past 4 years. I play guitar and sing. I really want to become a professional musician and get signed to a label. But I live in ireland and my chances seem so slim. There are no opportunity's here for someone like me,any musician except for the likes of u2 and the script and a couple others have made it and are successful by moving to america or the uk, the rest have not succeeded worldwide.I want to live my dream and perform. Although im not a confident person and I think alot of people would agree on that. But i dont want thats to stop me. I no i can work on that and I am. This is not some fantasy dream im completly serious. People often tell me im a great musician and that I have got the whole package(trying not to sound vein here)but I dont no how to make my dreams come true. Each day goes by and I feel like im letting it slip through. Theres not much I can do. I dont have alot of money so i cant move abroad and plus im too young. I practice everyday and its pretty much my life , I know thats a really cliche thing to say but its true. Its all want. Im so determined and adament that this is where i want to go in life. I keep on dreaming and praying and hoping, but sometimes I feel like hope is all ive got. So im asking you, do ever think its possible and how can I make it that way??
