Hello, Miss Abbey, you did the right thing in reaching out.
I am very sorry to hear that you went for so long without validation or help. My heart goes out to you for having to feel that old pain all over again. The feeling of being alone right at home in a house full of people is an awful thing, and your feelings are entirely understandable.
It is a good thing for your sister that she is getting help, and this could very well open a door to helping your mother understand your side after so long. Parents can be spoken to by counselors , and you can have your sister discuss your issues in the form of discussing her own. Your sister can talk about your problems and ask if her therapist can speak to your mother and suggest that she open up to you. It doesn't violate doctor-patient confidentiality and it is a roundabout way of getting a professional consultation.
If you can cooperate with your sister to get her to have this short conversation with her therapist, your mother would hear it from a professional's mouth to open up to you, and could make her more likely to take you seriously.
If you'd rather not take that route, you can always sit your mother down with your sister and have your sister explain things, since she seems more open to your sister than to you.
Whatever path you take, never let anyone make you feel like you are worthless. Never let anyone or anything stifle your will to live happily. You are among friends here on BlahTherapy. Most importantly, never forget that you matter, and you are not alone.
