So I go to this help center for people who struggle with employability, job stability, etc. We do solo counselling as well as group activities, volunteering, classes, etc. 

Couple months ago theres this girl who started an internship there. We see eachother sometimes during coffee breaks. She loves to converse, always smiles when she sees me, enjoys my casual flirting, all traits that stand out from miles away to my BPD. I asked her out right before the holidays and she  politely declined, said she couldn't accept due to professional reasons. I moved on during holiday break, everything went smooth. 

After holiday break, she acted like her usual self, very talkative and always looking for excuses to be around me. I try not to give her too much attention but when we see eachother's eyes she's like a magnet to me. 

I want to believe her internship is the only reason she said no, but at the same time she's such a nice person that it would be stupid to believe she's giving me special treatment. I really don't know if what I'm seeing is legit, or if my head is blowing everything out of proportions.
