Thinking of Dropping out

Out of the IB Programme, high school, the record in general. The stress and effort is piling up. I don't see myself working. I fear I'll just end up in the same position I am now. I don't feel I'm moving forward. Just kind of doomed to be like this forever. My mom would be disappointed. I have no motovation. Why am I doing this? I'm getting straight A's, what for? What will that earn me? A good job? Lot's of money? Then there is a chance of a retirement. If I live that long. What's the point? Has anyone else had this feeling, or am I alone in this?
