Make a commitment to one short term goal or activity. No one really wants to die they just don't know how to go on living right now. Write down this very statement and hand it to someone you trust. Sit down and write out every last feeling you have inside. Write as long as needed and each time you feel upset.
Life is all about gaining problem-solving skills.
You simply haven't lived enough of life yet to have those skills. If you can see your present suffering as transient and normal, it will give you ability to cope with predictable future conflicts. No argument adolescence can be painful. Like a roller coaster, you may have to ride it out. It may not be fun, but it will stop.
