For a bossy older sister, Kaila sounds so wise! She may get off track for a short time, but she refocuses and finds her peace and hope again. And Lorena doesn't give her sister any flak for ordering her around - indeed, she's intuitive and concerned about the "Donor" situation, the international legal affairs. Gotta love Lorena!
Your story is intriguing, leaving us to wonder if this "Donor" will ever find his place with zen-like Kaila. (You might need to spell it out more clearly that Donor is code for her daughter's daddy?)
I resisted the urge to comment on your punctuation (use commas, not periods, in dialogue, e.g.).
