So many good suggestions here. And while therapy is definitely a good option, I’d start simpler before spending money on that.
I’d ask one simple question: what are your sleep habits? Sometimes it’s as simple as working to get better sleep. Not more sleep. Better sleep.
If you wake up tired, feeling physically exhausted, then a few things could be at play: you may simply need to stop eating four hours before going to bed, and only drink water, but stop that like two hours before going to bed — and try to use the toilet before going to bed no matter what.
You could be losing sleep due to using a device when you lie down. Either due to time, stimulation, light patterns, etc.
And another, bigger issue, is sleep apnea. A few of the biggest symptoms of sleep apnea are: waking up feeling physically tired (like your arms feel like salamis hanging off, or you feel in a brain fog); falling asleep in the middle of the day for what seems like no reason; finding that to get through the day, you have to have a lot of caffeine to function; nodding off easily while driving; and the most obvious of them — waking up in the middle of the night as if you had to take in a huge gasp of air.
Sleep habit issues and sleep apnea are both major causes of impatience in a person. Source: myself. When I get better sleep (especially after I got on a CPAP), I generally became a more patient person and in many ways a happier person.
There will always be other stressors than the above that can factor in, but for my money, I’d begin there. The other suggestion of drinking more water is another easy first step to see if that helps. Exercise is also an easy step to take because it has the immediate physical and chemical effect in the brain of helping to ease one’s mind.
Everyone is different, but the above has helped me.
I wish you luck in your journey.
