It's good that you are reaching out to express your frustrations in life. You should not be thinking like that. This life is precious and full of opportunities and surprises.
You may feel particularly dejected due to different influences in your life, but it is all a matter of perspective. You have to learn to gain positive perspective. Everything may seem downhill but this is mainly due to your own perception of what others think or say.
You conceptualize success according to other people's standards or goals. You have to realize that people arrive at the definition of success by what they see on TV. In ancient civilization, success would be to eat well but over time and generation we have evolved into this self centered animal whose idea of success is determined by others.
You have to take a step back and realize how much your family loves you. You have to realize that you do not have to have everything that you see on tiktok or other social media to feel good about yourself. Self contentment comes from inside and you can work on it. Drive out negative thoughts and embrace positivity. It will not happen overnight but it's possible if you keep trying.
