I think my life is over
Why would you say your life is over?
I just feel that I have wasted my life.
I'm sorry that your life is in such a rough spot, but you need to keep going as this is just a bump in the road. It's not worth dying over this problem, and there is so much support you can get like with a therapist to get you out of it.
What's the point? I'm tired of working and studying, I was told I was going to be the best and get a good job. I'm not even able to get a job. I hate my life and hate everything.
I understand where you're coming from, but you shouldn't think about killing yourself. You really should seek out any kind of professional help you can find to help you through this.
