She went to a therapist 2 months ago and he diagnosed her with BPD but she shortly stopped seeing him cause she felt like she wasn't ready yet. The last time she went, he told her to do some sort of exercises and think about some stuff, but she couldn't do them so she stopped going. And now she told me she's thinking about starting again but she's not sure whether she's ready to do this or not. So i want to know what's best for her right now.
Should i encourage her to start again or is it better if she waits until she feels ready?

We are online friends, we've known each other for over a year but we became very close like 10 months ago and we talk almost everyday, but recently we met irl for the first time and after that she just starting talking to me in a different way, i felt like she doesn't wanna talk at all, she would just reply late and try to end the conversation. I asked her a couple of time if there was a problem but she said everything was fine, but then she kept talking to me this way and it made me very upset, so i told her how i feel about her talking to me this way and that i don't like it and that she should tell me if there's a reason for this or if she just doesn't wanna talk again. She told that she gets scared whenever someone gets closer to her, and  meeting me in real life after we were online friends also made her scared. We had this conversation the day before yesterday and we talked a bit afterwards. I want to know what i should do know. Should i try talking to her again now or should i wait and give her some time and space?
