Tell me why! I want the Ans Now!

You should know there is no real answer to this, and you should also know that this is not always true. Sometimes the first child gets all the stress and strain and the others that come after have it much easier, it's as if she has cleared a path for them to just sail through. If this is any comfort, just imagine that it could be much worse, you could have no parents, or parents that abuse you or you could live with foster-parents or have no siblings at all! It sounds like you do need to have a talk with your parents though, calmly and rationally, try and explain that you feel un-appreciated and you believe that sometimes your good deeds don't get the same praise as your sister's. Who knows? There may be something more to this than meets the eye. The only way to handle it is to talk it through with your parents. Try not to be over-wrought when you approach them. Let them see that their opinion really means a lot to you and you are feeling the loss of their approval and want to know why. I wish you all the best!

I agree with trinihd, you need to talk to your parents. You are needing their support right now. There may be other issues going on that you do not know about or are not seeing that will come out during your conversation. I am the oldest in my family. I have 2 brothers and a sister. I always felt like my younger brother, the first boy was treated better and was prefered over me. It was not the case but at the time it was how I felt. I also suggest you talk to your sister in a nice way and let hwe know how you are feeling also. You said you have 2 sister, does your younger sister feel the same way? Maybe she feels youa re the favorite over her. This can possibley be solved with a nice rational discussion with every one involved. Call a family meeting and get it all out of your system.
