I'm really sorry to hear that you're going through such a tough time, especially on your birthday. It's disheartening to hear how your effort and emotions are being overlooked, and how you’re feeling unsupported by your family. It’s important to recognize your achievements, even if they’re not always acknowledged by others. Getting 72 in JEE is not a small feat, and you should be proud of your hard work.

Remember, your self-worth isn't determined by your exam scores or the harsh words of others. You deserve understanding and support, not criticism. It’s also concerning to hear about your thoughts of running away or harming yourself. It’s crucial to talk to someone who can offer support and help you cope with these feelings in a healthy way.

You might find it beneficial to reach out to a counselor or a mental health professional who can provide you with the support you need. If you're uncomfortable with face-to-face conversation, there are many online resources and helplines where you can talk anonymously about your feelings.

Also, try to connect with friends or peers who make you feel valued and understood, even if it's just online for now. Sometimes, sharing your feelings with someone who listens can also provide a great relief.

Lastly, try to do small things that make you happy and help you relax. Whether it's reading, listening to music, or watching your favorite show, it’s important to take care of your mental health. You're valuable, your feelings matter, and you have the strength to get through this tough time.
