Betta Fish: I have to put my betta down today and I’m heartbroken

I've had Dr Shrimp Puerto Rico MD for exactly 11 months to the day. These pics are from right when I got him. He's been rapidly declining with dropsy despite attempted treatment. I can't stand to see my sweet boy continue to suffer. He's pineconing, breathing very fast, and only ate when I put him in a small cup and pushed the pellet down so it literally landed right on his mouth but he wouldn't take more than just one pellet. I love him so freaking much. He's definitely leaving a Shrimp-sized hole in my heart.
