How can I (21 F) heal from a breakup with my ex (26 F) that suddenly happened last Sunday due to her feeling lost and wanting to find herself?

The thing is, she is very selfless. No matter how many times I reminded her to not always think about us, due to my fear of her getting too tired, she always worried about me. She always thought about me, her friends, and family. She forgot herself. She no longer have any hobbies, lost motivation, felt no eagerness to do what she used to love doing and watching. Her depression and anxiety got worse due to the quarantine in our country - where she had to spend every single day with her family.

Backstory. Her mom and stepdad are no longer in good terms. Her mom is seeing somebody else for years now but she cannot tell her partner (my ex's stepdad) because they have a daughter who just turned 12 or 13 last December. So all these years, my ex was the one keeping their family at peace. But she was so tired of everything. And the quarantine just made it worse. It has been extended forr 2 times already and it probably would be extended again.

The thing is that, we still love each other. But she was so determined to end things. No matter how hard I tried to convince her that she just has to focus on her goals while she is with me, she would not agree. She told me that she does not want to think of anybody else while she is chasing her dreams. She felt like what if by 30, she would still be living with her mom? She felt so left behind in life. And I had to be sacrificed.

TL;DR: I know this is the end for us. We are about to celebrate our 2 year anniversary by July. But this happened. We planned our future together. We told each other that we would spend our always and forever together. We invested so much time, effort and love. And we suddenly broke up. I keep hoping that she would come back but she is already so determined.

How can I move on? How can I stop hoping for her to come back? I just want to heal. I just want to be okay. I feel so miserable because I did everything to make her happy. No matter what I read about moving on, I still feel so empty. Can you tell me what you guys think? And if you had experience this too, what helped you? Did you guys get back together?
