I have some experience with this having had a very sensitive V.
What you need to help her with is her confidence. Exposing her to as many different people and experiences, making sure all the experiences are positive is the best help you can give her. And it's important to do this when she's still young.Taking it slowly not to overwhelm her.
I hadn't realised how important this is and as a consequence my V became very fearful of many things. For example although I took her to work with me every day where she met people, other dogs and horses it was the same experience for her every day. When I took her on a new walk with cows in the field she hide under a thick hedge shaking with fear because of the cows.
The good news here is that with gentle exposure even phobias can be overcome. She became indifferent to cows, took years! And her life long vet phobia was overcome in the last year of her life with her being hand fed chicken by the vets when she had to stay overnight.
