Don’t do it. Please. I had depression and thoughts similar to yours and I was really considering doing what you want to do. I thought life was hopeless, and I thought it would never get better. When you’re depressed, it clouds your judgement and really makes you think that your life will never improve- it’s not true. Please just wait it out, as painful as it is. I hesitated and waited, and 2 years later I’m the happiest I’ve ever been. I’ve met new friends, a great guy, and I have a great future ahead of me that I never could’ve predicted. None of this would’ve ever happened had I decided to end my life. No matter how far away a future seems to you, you have one ahead of you. You have people to meet, and a life to experience.
Just wait it out, it may feel like torture but if you kill yourself its a permanent solution to a temporary problem, and you’ll be hurting everyone else around you. In the meantime, try doing charity work and try yoga. You are loved, and you are important.
