First time ive seen a thread or discussion like this and not felt like part of the club. I've come a long way.
Some things that helped me;
Eating better. Even soon after I started trying to cook for myself more and eat properly, as well as eating with my family and friends more, I became markedly less irrational day to day. This was actually really hard to keep up. Sometimes my brain didn't see the point in sustaining my existence, id eat as little as possible, bland food that took no prep, just to get it out of the way. Now I'm going out of my way to try new things, learn to cook, my body is a lot happier with me. I get so much more energy throughout the day, and when I have it I find it hard to sit around and not use it.
Go outside. I live in the countryside and think this is a better option for people who do rather than citydwellers. I personally have always found cities claustrophobic and stressful. The difference in air quality between boarding the Isle of Wight Ferry, and then stepping off a train into London when you've been sealed in the train for a couple of hours - It's like breathing stale water. Get outside, even aimlessly. Walk, explore, make your body work. Get tired. Physical fatigue can win out when your brain doesn't want to let you sleep. God, the sea is good. If you have access to it, and there is a day that water is mildly palatable, get in there. It's invigorating. Some people have never seen it. Some people would kill for a tranquil place to spend an hour.
Smoking weed. Ah, the biggy. Be honest with yourself. What's your relationship with drugs? Drink? Do you enjoy drinking, smoking as much as you do? Is it the same as when you started? I had to face these questions, and the answers were bad. I thought my smoking habit was relatively healthy because I didn't drink, and alcohol is what will kill you, right? But a huge portion of my waking hours were based around weed, either getting it or burning it. I had no time left in my brain to think about myself, things I want to do and achieve, and as soon as I did have the time, I was stoned and distracted, and probably thinking about pointless ****. Now I smoke in only a few situations; a party, where I still much prefer smoking to drinking, I am a very embarrassing drunk which I consider a lucky strike as I'm unlikely to ever have a dangerous relationship with alcohol. I smoke after, and only after, a hard day's work. Those days I have to myself I no longer wake up and roll a joint. That just writes your day off. Trust in your own company, learn how to have a good day with yourself.
Finally, I stopped trying to heal the world. I think growing up in a time with archives of information at our fingertips, news stories spreading in moments that used to take days, has had a profound impact on our generation. We've concerned ourselves with all the great problems of the world - the injustices, struggles, great problems we face, have been in front of us, unfolding before our eyes in closer proximity than any other time in history. Kids discuss the economy, social reform, geopolitics from a younger and younger age and it's my personal belief this has been a factor in the skyrocketing of mental health issues. I tell myself this - I am who I am, where I am, and this is what's in front of me. There are problems everywhere, globally, nationally, and locally. Very few of them can I actually affect. So those that I can't, I try to focus on the positive. I try to believe there are good people in powerful places. Good people aren't loud. We focus on the loud, and therefore the bad, while good people keep the world just about ticking away. Not through any concerted, grand effort, but by dealing with what they know, what's in front of them, and what they can realistically affect. I can't do anything about disenfranchised youth, unemployment, war, famine, but I CAN do something about some things. I can clean up my room, I can help my family and friends, I can make my voice heard about local issues. So I did some of these things, started litter picking the footpaths around me, not for any compensation, just to see them look nice. I helped a friend take apart a whole mobile home sat decaying on his land, and refused when he offered to pay. That process, of putting in physical work and seeing tangible results as we reclaimed a huge patch of land that he can use to grow all sorts of things, that process itself was payment enough.
There will always be wobbles. Bad days happen. Sometimes for no reason. But you can and will take control of your thoughts and by extension your life. And this life is worth it. This place is so wonderful we still can't make sense of it after thousands of years, endless progress, probing, questioning, proving ourselves wrong. I want to be around to see what else we are wrong about, what surprises are around the corner. That's not how I used to feel. Everything was so predictable, I'd been promised I would do great things and go far, I failed, on my own terms. (i was a very smart kid and a not very smart teenager). But I'm young, **** knows what is in store for me, for the world.
I appreciate this post might not help you. I can't guarantee what works for me will work for you, but if even one of you thinks one part of this post was valuable, then it was worth writing.
