Thanks, Diaminohexanoate and BECCALICIOUS for giving me these awesome advice!
My friend and that guy, from what I see, they are together again. But I am still a bit worried about her because she has lots of problems to deal with in her life.
But on the other hand, at least she is not so depressed now.
And I think you are right, maybe I should just give her a little hug or a gift instead of pressuring her to speak to someone. I mean, it is her own choice. I hope she would be fine after today.
Thanks for all you guys' help! It really made me feel better when I wanted to help her alone!
