stuck in the middle

It has been some time since i have grumbled about being the middle kid. I mean, everyone has their own share of troubles, and being in the middle does not, in any way, imply that i have a sucky job. After all, i have the best of both worlds, rite?
BUt this time, it's not just about being stuck in the middle between both my siblings. it's about being stuck in the middle between my sisters and my parents. i KNOW my mum is delusional about me being the "peacekeeper" of the family (because i am in the middle), but don't you agree that it is a little heavy to counsel my PARENTS and give them tips as to how to help my OLDER sister AND younger sister? Not that i'm special, my mum does this to my older sister, too. BUT. How am i supposed to help? I feel kinda helpless and young. I can't do this. This is my family. You can't just give your two cents worth and scram. you have to tell the truth. In the most loving, Christianly way. And it doesn't help that i'm kinda busy rite now, and i have had to reject my younger sister's birthday invitation to do chinese project. We did celebrate last night, though.
God, you say "ask and it will be given unto you". I ask that you protect my sister and surround her with loving, Godly friends, and that you will help her to study VERY hard. I ask that you will give my younger sister motivation to study hard too, and help her to grow up to be a Godly teen who loves U with all of her heart. And i pray for your wisdom to act as a middle person, and i pray that i will find the balance between work and family and i pray that i will become a doctor.
