'Difiiculities'

I don't know what to do. Every time I try so hard and it ended up with failing. I don't know what I went wrong, I feel so guilty for let down my parents. I really want to be like my sisters and my brother. I'm scared of failing again. Every time I keep trying the results is always disappointment.Although people said that 'Failure Is The Ladder Of Success' but I don't have anymore strength to get through this anymore. I just hope that one day God will hears my prayers. I don't want to disappoint my parents anymore,eventhough they always keep cheering and supporting me eventhough i failed so many times but I want them to be proud of me and not shame of me. I wish i could turn back times and make things right. I hope they forgive me.
