I lost my bird, it's devastating

 Harley, my cockateel just died due to cold temperatures.  Last year I would turn on the heat, I don't feel like doing it for some reason, I like the cold, but clearly she didn't.  I 'm crying because she gave a last chirp that could of possibly be heard all over the apartment.  It was her spirit saying goodbye, I don't deserve such amenities, that's what makes it a conflict in my mind.  I had an awesome time with her, sharing my leftover food, letting her sit on my lap or my shoulder.  I feel dumb, really stupid.  I hope I can recover, no one will read this but me, and let that be my therapy.
