Grief and not-so-happy endings

I'm having a rough time right now because I just finished a fantasy romance where the ending was NOT what I would consider a happily ever after. There was some ambiguity at the end, but there was a lot of grief, too.

Here's the thing. I don't do well with loss or grief in my fiction. I've been through horrible grief IRL after unexpectedly losing family members, and it led to PTSD. One reason I read romance novels is because they feel safe to me, because I can expect a HEA. So feeling like that's been taken from me has me kind of upset.

I guess I'm looking for some encouragement or helpful suggestions, because this has made me not want to read. Grief affects me so profoundly at times that I'm afraid to read another book and have this happen again. Is there anything other folks do to combat this? For reference, this book was simply tagged as a normal fantasy romance on Goodreads.

Right now, I have three other books I was planning to read: The Undertaking of Hart and Mercy, Deal with the Elf King, and Assistant to the Villain. Do any of these have non-HEA, or horrible grief? (Spoilers are fine) Because if so, I'll simply avoid reading them.
