I think that's a bit harsh on her. She has a problem that the OP would understand.

How to regain the trust of someone who usually doesn't trust people?
Like I said, I don't know the answer. I'd think of being gentle and patient, maybe apologizing for being inappropriate, and gradually rebuilding your friendship. I'd think that if you want her to believe you are sincere in wanting to be her friend, it would be a good idea to mostly try to be her friend, at least for the time being.
Then again, there's friend zone and everything...

I'm sorry, I can only make naive suggestions for problems like this.
