Should I get help, since I nearly took my own life today
Why do you want to  commit suicide?
I was upset with a decision a friend made, a video game I played and a relationship I was in.
Yes, it sounds like your troubles were just piling up. It's never good to get close to taking your life. Perhaps you should see a therapist.
No. I'm going to pretend nothing ever happened and just keep on doing what I'm doing.
You really shouldn't just pretend nothing happened. It's better if you could try to find a doctor to work with you in getting better. You don't want this to happen again do you?
