what's the opposite of bittersweet?

Something that's bittersweet is usually mostly sweet and pleasant but a little bitter. What's the opposite of that, when it's mostly god-awful but a little sweet too? That's how I'm feeling about Alison Piepmeier's passing.

What a fantastic woman. So amazing, so energetic. What a smile, what a laugh. She's one of the few heroes I have. Always willing to stand up for injustice and not easily intimidated.

Her writing was always so eloquent and easy, smart and informed but also with a tone that reached out to the common reader. Her productivity was a good reminder: shouldn't you be writing? I watched on her blog when she first got interested in zines, then talking at conferences, and then suddenly a book was out. WTF? And I was still working on a single chapter. *laugh*

What she did with Maybelle, I couldn't have done. She made it possible for her child and many other Downs kids to lead full and happy lives. She certainly educated me that Downs doesn't have to be a curse. She didn't love Maybelle despite her Downs Syndrome; she loved it as part of Maybelle. Radical acceptance.

I'm sad she's gone. I worry about Maybelle. I wish she could've stuck around to mentor more students and teach us more about love and acceptance. But if you've gotta go, I want to go like she did. Surrounded by her family, all loving her, as she lies in bed and slowly slips away.

I feel some grief but honestly it's mostly love and gratitude, so I guess "bittersweet" is the right word after all.
