Why do I feel so resentful?

My grandparents are gifting money away to all of their grandchildren this year. The reason being is for tax purposes. Each grand children will receive 26,000. Each grandchild’s spouse will receive 26,000. And each grandchild’s child will receive 26,000. I am not married and do not have any kids. I am the second youngest (25) of all of the grandkids and I have 130K in school loans. I have sister who is married with a kid, owns a house, and her and her husband make good money. I will only be receiving 26K while my sister’s household will be receiving 78K. Essentially she will be receiving 52K more than me each year just because she is married with a kid . . . . Ahh! I feel incredibly resentful about this and whenever I try to voice my opinion I get treated as though I am a spoiled brat.

Now do not get me wrong. I am incredibly grateful for anything anyone ever gives me and I do not feel entitled to any money at all. I could sure use the money, and I am thankful to be receiving anything at all. But at the same token I feel as though they are setting up my sister and her family for life and leaving me out to dry. I just do not see how that is fair. I at least think they should figure out some way to remedy the situation and make it a bit more fair for me.

What I want to know is am I acting like a brat for feeling this way? I just need to hear what people have to say about this. I just can’t help but feel incredibly resentful . . . I almost just need a break from them for a while. It is hard for me to be in the same room. What do you all think?
