Help me make my dream

I am 15 year old boy from Tunisia. I am born in a lovely poor family.

My dream is to visit the USA or Europe but it's impossible to share that dream with my family as we are poor.

The summer is almost getting the end and I want to make a trip to anywhere. As i think about that all the time i become nervous and so depressed.

Sometimes at night I start dreaming how i get on plane and land in strange country but when i realize that , it's impossible to make it happen tears invade my face.

Please help me ! :/
