Here are my two cents

1. Abstain from cheap dopamine. This includes alcohol, weed, cigarettes, Netflix, social media, etc.
2. Build a healthy routine including sleeping and waking up early, walking daily in the sun, working out, and eating healthy. Lastly, I recommend journaling daily before bed, jotting down one win of the day, one point of gratitude, and one point of frustration.
3. Pray and get into practicing your religion. You'll find peace in that regardless of your beliefs.
4. Acceptance. Learn to accept your current situation and build from there.

You'll be rock solid in no time if you manage to do the above.

You're doing right. Most of people won't understand you however there're people who feel the same pain inside.
Don't be silent talk to people, 5 people out of 100 have the same waves as you.

We just want to know the answer to the main out question - What is the sens of life? And when we can't find the answer brain screams - LIFE HAS NO SENSE.
But it's not true. Life if perfect and you'll get as fast as you start to understand other people...

We are merely surfers on a giant spinning rock amongst billions of other giant spinning rocks and exploding balls of hot gas in an endless universe. Try not to let the tribulations of being human beat you down.

I understand darkness. I have walked through it myself. Although our journeys may not be the same and our darkness may not be the same here is some advice I can offer.

1. Don't lose a sense of wonder- go out in nature look around.
2. Every day do something positive for yourself- take a walk, do a workout, read a book, listen to a podcast, find something that makes you laugh, meditate, journal, play music. (Everyone needs an outlet)
3. Stay away from Alcohol, drugs, gambling, excessive social media exposure.
4. Spend time with positive, productive people.
5. Keep busy. Tire yourself out so you sleep well at night.
6. One foot in front of the other. Win each day. I haven't had a drink in over 9 years after many years of drinking far too much and being miserable about it. To get to day 3,375 I had to get through day 1, then 2, so on and so on. Good habits compound.
7. Sometimes you just need to seek professional help. Don't be ashamed if you do.

Hope this helps in some way.
