Should I let go?

Anonymous
I got ghosted by my best friend. I knew her since 2020 and ever since we've became close. She's literally what every best friend is, caring, loving and is willing to listen to me all the time. She knows me so much and I know her too. But then she suddenly ghosted me out of nowhere saying that she needs to take a break. She even ghosted her other friends as well. I really miss her considering she's my favorite person and I can't let go of her ever. I tell her about my problems every time and I can't go a day without talking to her. But after she went I don't know what should I do. My days are becoming more depressing and I really miss her so much. What should I do? Will she be back someday? I know I can't ask her these questions but I can't stop but think.
