Please do not loose heart. You are very brave and I am very proud of you that for your parents sake- you gave up your interest and took the subjects they wanted for you. I respect your feelings
. And I strongly advise you to -respect yourself. You deserve it. How few children are there who go by the wishes of their parents. You are one of those few!
so, be proud of yourself.
Next, you could not carry on with their choice. Does not matter at all, because you tried to give them happiness but could not cope with the change. This is perfectly acceptable as we are all like that. Many times we fail to do well in a stream we dislike.
I recommend talking it out with your parents, trying to tell them what makes you happy. Seek help of a good counsellor and go for interest and aptitude testing. Based on these question-answer tests you will find your strengths and weakness and get guidance on which stream is best for you. If you want take a private online consultation with me alongwith your parents.
