Stop staying up so late.
Here's how get back on sleep schedule.
1. Stay up for 24-48 hours until you are really tired.
2. Set an alarm for a reasonable time. If I don't have to wake up earlier, I'll set my alarm for 9AM.
3. Go to bed at a reasonable time. I try to go to bed by 1AM, but make sure I'm in bed by 2AM.
4. Pass out from sleep deprivation.
5. Wake up at that reasonable time. Not get up, turn off alarm, and go back to bed.
6. Function as normal during the day. PROTIP: Despite how tired you might be, don't take naps!
7. Repeat steps 2-7 until you are sleeping regularly.
Other tips: Eat healthy. Drink less alcohol. Work out (don't push yourself to hard).
Also, the night time does things to a man's brain. Makes him have crazy thoughts. You start to stare into the abyss that is the future and realize that you're simply looking at a wall. You try to diagnose yourself, figure out why everything is wrong. Realizing you'll never come to grips with a cure, your only escape is unconsciousness, in the hopes that everything will be better when you awake. The fact is, the next night will be the same. We tend to think that life is a walk, by looking at the negatives we can try to step around them. However, life is more like a plane flight. If you're focusing on the ground, you're not going to go anywhere. Once you start looking up, you'll notice that most the problems will seem to disappear. Instead of focusing on what's "wrong" in your life, look at the bright side.
"Chaos brings order. Who will you allow to lead you blindly till the end? You're like a little girl with a stupid crush. We all sing glory. We all choke ourselves with our own ignorance. There is so much more to life than your stupid desires. Nothing is everything and everything is something. Confused? Troubled? Find the meaning is looking through the vivid transparencies. Dance the night away because tomorrow we will look back and talk about good times now gone forever. Trace lines around the image of your choice. Dance until the end my friend and find joy in every living thing. Optimism is not a choice, it's a belief."
Be grateful you're alive. Be grateful that you have limbs and are not permanently handicapped. Instead of judging, calculating, and fighting other people, try to enjoy their company and heed what they have to say. In the end, the changes you're longing for start with you.
