And also, special thanks to everyone who has been so supportive of their message. I can understand this means a lot. Don't lose patience and hope everything can be achieved with hard work and hard work only pays when you do it on a right track. You seem like a great boy who loves his family and I hope they love you the same that's why they shifted you to a better country in hope that you get a better life. You can learn any language or subject with ! with reasonable price. Don't waste time on what you don't know, instead move ahead with learning and grow better each day.
