I found myself in a position not unlike your own a decade ago when I was your age. Then I got a tumor in my throat and had a radical perspective shift. Five words effectively saved my mental health. "One must imagine Sisyphus happy". This is a phrase from an essay by Albert Camus called The Myth of Sisyphus. There's no fix. No correction or cure. There is only how you view the world and I have found that by going down the rabbit hole with camus' interpretation of the greek myth of Sisyphus has helped me take control. For me that's living alone with my cat. Indulging in introverted self improvement and limiting my contact with the outside world. It's not a defeat, it's conditioning. I am aromantic so don't pursue relationships or the stress of them anymore. My core drives are self understanding and self improvement and I sleep fine at night now. Haven't drank alcohol in years, and full disclosure weed does wonders for me personally. One must imagine Sisyphus happy. I wish you luck. Keep that chin up. Because tomorrow the sun will rise, who knows what the tide may bring - Castaway
