Dir96, you have been GREAT to talk with a specialist! You have been really brave doing this, and also talking with your mom...I understand that it's embarrassing. Maybe she said that because she wad worried for you...when she'll see that seeing a therapist helps you to feel better she'll agree with you. And if she however doesn't understand, don't listen and go on seeing your therapist, it's surely the best thing to do. But I wish you that she'll understand .
Best wishes for everything
