My mother always blames am acting as her enemy ...

If I understand your question correctly I would say that your mother is acting quite childish. If I were you I would tell your mother that your relationship with her is too important with you and you want to do everything that you can to fix it. Then suggest seeing a family therapist together. This will bring someone else into the picture to be able to view and give an unbiased opinon. Think about it. I think it can really help you. Good luck.

It appears to me that your mother is mentally disturbed.

Please remember that all parents don't remember what it is like to be your age, or were not allowed to be as opinionated as young people are now , without recieving a negitive response. Please remember to be yourself. Pull your mother aside and in a calm fasion tell her how you feel please start this talk with letting her know how much you love her. But just as a measure of respect try not to so opinionated around your mother. Many times more than not a parent negativaty as defense, most likely from a sense of losing control or no one likes to see babies grow up. But also realize that you wont live with her for ever so try to get along now . Some day when you are older you will be glad you did. Even if  it doesn't work out for the best you have atleast tried.

Sandhya, You are not going mad. Your mother is not able to understand that you have many questions. She may not be able to because of her nature and upbringing. You, however, must always remember that to be curious is O.K. and continue to ask questions. You have  a wonderful mind that also must understand that there is a time for questions and a time to be kind to your mother. Do not expect her to do what she cannot do. Just love her. No one person can meet all your expectations. She will be able to do the things for you that she can. Conflict arises when you see her frustration and want something more from her. This is normal for you to feel. Moms sometimes can't do anymore than they are able to do. There will be places and times in your life where you can talk in less challenging circumstances and exercise your ideas more freely. You may not be able to do that right now at home with your mom and family. Don't force it. There is a time and place for everything. You may have to wait for the answers sometimes but be patient. It's hard to be smart. Your mother must think that you, too, are adorable. I do.
