You indeed seem to be very disturbed. From what you report there seems to be lack of communication between you and your family members, specially your mother. Many a times it happens that we misperceive the actions of others and this in turn colours our perception of everything they do say. Since you have reported that you have tried speaking to your mother but it hasn't worked out, I would advise you to approach your sisters and see if they can help. Tell them about how you feel and ask them to help you out. It is important that you communicate your feelings to your family members, may be it helps you to understand and look at things differently. If this doesn't work out then you can take the help of a professional psychotherapists for the same.
