I will try to summarize it as short as I can. Please bear with me. 

I called a girl about an item she was selling on e-bay. Turns out I won't be needing the item she has and I'll be new one another version from a shop. But somehow we hit it off through text messaging. We literally sent hundreds of text messages back and forth, as well as 20 minute calls here and there. 

After 4-5 days I invited her to furniture shopping which she definitely showed interest but couldn't make it. Then she invited me for some beers with her close friend, but then her friend got sick and they went to the hospital (not an excuse, as she sent pics). 

At some point in our conversations, she opened up to me about her BPD and some other private stuff as well. One day she really hated work and was ranting to me through text telling me that she wanted to quit etc. Then a few hours later she was fine. 

Anyway, for the last 2 days she has been very distant, not even reading text let alone replying. So I sent her a few messages to ask if she was doing OK, how she was feeling. She said she wasn't feeling well and it doesn't have anything to do with me. So I told her it would help if I could at least hear her voice. A few hours later she calls and we talk like an hour straight. She sounded OK to me but she said she was feeling really bad and things were spiraling out of control and that she was going to see her shrink the next day.

Now 2 days has passed since that conversation and she's still very distant and I don't want to put her under pressure or anything, but I'm a little worried about her. Tried sending her messages like 10-12 hours apart. Asked if she went to her shrink etc. I got nothing. Then tried calling but again nothing. 

After that she texted me that she wasn't feeling well and if it would be OK if she got back to me later. And I told her that I was just worried and I'm there for her. 

Now another 24 hours passed and I haven't contacted her. I'm gonna let the weekend pass without communication. Though I'm not sure how I should approach her, as I definitely do not want to pressure her. 

Any advice on this would be greatly appreciated. 

Thanks
