I understand your worry and concern but to get answers, you may have have to take a chance. It may surprise you that being open and honest may be the most beneficial for your needs. It may be possible that your mom is worried about what you might think and you are worried about what she might think! I have found that uncomfortable communication is usually better than no communication.
Disclaimer- this its only my opinion and you need to decide what is best for you and your future- I am not a professional...
