How do you get over being sad from losing a pet?

[Squirtle]

Today, my mother made me give up my Albino Burmese Python to her boyfriend who has NO CLUE at all on how to care for big snakes. She made me give him up because I'm starting my senior year in high school next week and says that I have to focus. He's not going to be away from me for long however, he'll be coming back home in December. I can't stop thinking about him AT ALL, every time I go to YouTube, at least 5 of the people I'm subbed to have videos uploaded of their burms.. and for some reason they let my retic stay at home with me. What can I do to get my mind off my burm for now? every time I go inside my room and see that big empty space where his cage used to be I just feel my heart breaking bits by bits..
