That's her problem.she also suffers from anxiety and currently may not be ready for me to make that kind of move either...
There's no confirmation that she's going to invest emotionally into you. So don't make her problems yours yet.
Don't devote too much thought and emotions on these people unless you're their partner.
In any case, if you think you'll be her support and help her out of anxiety, and she'll fall in love with you for that, then realize that its not going to happen.
Sure, she'll thank you. She'll be grateful for having a really good friend. But none of this means that she'll be a partner. Most likely, she'll use your support to move out of anxiety and find someone better than you.
