Why do I feel depressed after ending a relationship even though it was the right choice?

Because you're grieving. Mirabai grieved Krishna—the absence, the incompleteness, the love that couldn't be lived in the way she wanted. She didn't stop loving to make the grief smaller. She held both. Right choices still cost us. You can know, deeply, that leaving was necessary and still feel the loss. That's not confusion. That's integrity. The depression you're feeling isn't evidence that you made a mistake. It's evidence that something real was there. Give yourself permission to mourn. There's no timeline for this. Some days you'll feel clear and free. Other days you'll miss them with your whole body. Both are true. What matters is that you're not using the grief as a reason to go back—to undo a choice your wiser self made when you could think clearly. Let yourself feel hollow for a while. Move your body. Be around people who don't require you to explain or justify your sadness. And know that this depression, intense as it is, will shift. Not vanish. Shift. You're rebuilding yourself on the other side of this love. That's sacred work, and it's hard.
