Why is life so unfair

We closed on a house a couple weeks ago and specifically bought this house because it had an empty lot next to it also for sale. We’ve been working hard to get the land cleared, graded, sodded and the fence will finally be done today. We move on Saturday. My best friend of almost 14 years is FINALLY going to have her very own yard!! 3 days before we move I found out she has an aggressive type cancer. She has been with me through everything. Every bad breakup, moving out of state and she was even the “flower girl” at our wedding. We finally got her the yard she deserves and I’m so heartbroken knowing she won’t be able to enjoy it for very long 💔
