A made up mind can be forced or could bend due to situational ethics but can never be convinced. I have hope in you and you also need to have faith in yourself and whatever you intend to do or become in life, even if others didn’t see anything in you.
Don’t give up because of them, it’s your life; not theirs. They won’t live it for you, and they can’t die for you either. Killing yourself will only make things worse. This world will never be a better place without you, that is why you were born.
You must proof to Nature that it didn’t make a mistake for bringing you into this life because you escaped been washed away like a sperm or through miscarriage. Try once more to bring a solution to your problems because I believe you can do it.
