Should I go on about ending my life because I can't stop thinking about it?
You can't be serious. Why do you want to end your life?
I'm a burden to my family and friends.
Ii understand that you think you're a disappoint to your family and friend but you don't have to hurt yourself for that. You should seek professional help if you have suicidal thoughts.
I won't die then. I'm planning on living a long life
I'm glad you're reconsidering your decision. I believe you really need to see a therapist for this, because won't your family and friends miss you dearly? How about opening up to them too, your relationships can get even stronger.
