Aww I am so sorry. I have had more pets than anyone I have ever known, and losing them is the hardest part. Was your bunny an outdoor bunny? Poor thing, the heat is a big danger for outdoor bunnies, and indoor as well. Much more of a worry than the cold. Poor animals. As for the puppy, did you have to put him in a shelter or something? Is there any possible way you could go and visit him? You have every right to be upset. Maybe you should take some time and sit down and think about the fun times you had together and all the good things. If you cry, cry because it is expressing your feelings. Once you remember all of the memories, you might want to write them down. Trust me, it helps you. Listen to how many pets I have lost:
5 Bunnies, 4 Hammies, 4 Gerbils, 3 Guinea Pigs, 1 Cat, 2 Dogs, 2 Bettas, and tons of fish.
Once again, sorry for your losses.
Britt, Floppsy, Lady, Sally, and Kelsey
