edit, I returned home, feeling physically exhausted, but I just couldn't fall asleep.
Every time I closed my eyes, I saw Spring lying weakly in the hospital bed, waiting for a blood transfusion. After finally managing to doze off for a little while, I even dreamt of Spring crying and looking for their mother. I woke up drenched in cold sweat, unable to fall back asleep.
I know something is not right with my current state. It seems like I have truly become attached to Spring. Even though I know Spring has their own mother and is not my child, I can't control my emotions and treat them as if they were my own.
