I would say to her: “I'm glad to see you again, I missed you a lot.” Let me tell you something, despite everything you've been through, you did very well, I congratulate you. You never let yourself fall into a pit despite the fact that your relationship didn't work out, that you didn't have the right job for your university career, and that many things didn't turn out the way you wanted them to.
You're going to do well after that failed relationship; you'll even have a beautiful daughter who is your life and your joy. Spend more time with your sister and your dad; unfortunately, they're going to leave this earthly life suddenly, and you won't have time to say goodbye to them. Keep yourself in shape, keep exercising, even if you come home from work very tired. There will come a time when you will work in a place where a sedentary lifestyle is your daily routine and you will have little time to exercise; even so, you will try, but it will not be enough; feel more encouraged.
And I want to tell you something: I am proud of you. You have handled it very well. You have been strong when you had no idea you could be, and now you are super happy. You have earned it. I love you.
