I'm lost in life right now. Is it appropriate to let this known to the world?
Oh yeah? That is somewhat disturbing. It is true? Why do you feel lost?
Because I don't know what to do with my future.
I understand it can be difficult to know what to do with your life, but you can't dwell on that. You should talk to someone if you're struggling to decide what you want out of your future or you may miss out on many opportunities.
I'm old enough to know what I want. I want to party and not get a real job.
Feeling lost in life as a result of what you want now is normal, especially since you have no desire to get your life on track. Build your self confidence levels up by being productive and leaving the teenage desires aside now. Get some professional help if you keep struggling.
