Book recom where the protagonist loved someone who died and she has a tough time loving someone again?

As the title says, looking for a story/novel where the girl falls in love with someone or has a crush on someone who suddenly dies, leaving her devastated. The girl convinces herself she’s loveless and would never find love again but destiny has something else written for her.

Im sorry if I sound CRAZYYYYY but anyone of you have something like this or similar in mind?
