I must be greatful to you for seeking help for yourself by asking a question. this is the beginning of your treatment
You will clearly improve in "inner happiness", "functioning", "academic performance", "excessively watching movie" etc., if you are in regular touch with a psychotherapist /
psychiatrist.
we often such cases like you, yours is nothing uncommon
You may be benefited by medication, that will be decided after thorough assessment of your life from birth to till date, and of your mind, by your psychiatrist
I presume, you would worsen, if you do not seek treatment
Kindly, do not treat this answer as a general nonspecific answer.
I would be most happy if you give a serious thought to this discussion
Wish you a happy life
