Friend putting stress on me

So me and my best friend are so so close like she’s ride or die. And we are always there for eachother and I lover her sm. Whenever she’s crying or upset I drop everything to help her no matter what. And I love love helping her but recently it’s been a lot. I’ve had a lot going on in my life and when she’s crying 2 times a day over a boy or random drama, and she won’t tell me the whole story but looks so crushed idk what to do. It sucks seeing her upset and I what to help but I honestly don’t know how to at this point and its all putting so much extra stress on me and i need to keep helping her but ig I just needed to rant and this seems a good a place as any. 💓💓
