Why can't my mind stop thinking when I'm trying to sleep?

It is difficult to sleep when you have a lot on your mind. I find writing it down helpful so I can process it with a fresh mind after some sleep.

I'm just an over thinker. I run scenarios a 100 times in my head before I finally fall asleep. It can suck most of the time.

This can be for many reasons. One being have you being using alot of electronics before going to bed e.g on your phone if so try not using them an hour before you go to bed so your brain can relax. Other reasons can be stress related or anxiety.

In my experience its because something is worrying me and being in a quiet room lets me listen to my thoughts more easily

Imagine a beautiful setting, anything you like, a beach Island. Take 4 breathes in then hold it for 7 and release on 3. This breathing technique helps you calm down, as well prep your mind that it's time to sleep.

Well, there can be several reason why you're still thinking while trying to sleep. From personal experience: I try to stop stimulating my mind by being online, watching TV, etc. an hour or so before sleeping. Being online just before sleeping is one of the most common reasons for your mind to be awake when you're trying to sleep. I would do something calming just before sleeping such as a relaxing bath, praying, chanting a mantra, reading, drinking chamomile tea, and just lying down and let thoughts pass without letting them take over. Also, making a to-do list can help as this is what might keep us awake for quite a bit. These are just my suggestions though...

Is there anything that Is on your mind? Before going to bed, have a nice cup of tea maybe even draw out or rite out your problems that you'e thinking, if not you could always take sleeping pills to help you out.

There can be many reasons, maybe you're anxious, and stressed. Maybe you've had a lot of caffeine in the day. Maybe you need to relax more. Only you can know.

Meditation is an excellent way to power down at the end of the day in preparation for sleep. There are several free apps that offer quiet meditation. Also, make sure your environment is conducive to rest. (ie no light from televisions, cellphones, etc.)

There are multiple issues that can keep the mind active, or over-active when trying to sleep. 1- Too much energy. You haven't used all that power God gave you for the day, so when it comes the time to sleep, your mind is trying to burn that extra energy left. There's too much. 2- caffeine. I don't need to explain that one. It's best to keep away from caffeine when the day is slipping into the night. 3-stress. Built up stress doesn't take a rest. Bathing before sleeping can help relax the muscles and mind. 4- Internet. It's recommended that you turn off your devices one hour before you go to sleep. Playing video games, going on Facebook or whatever you may be up to, is re-awaking your mind. It will not help you sleep and should not be a means to help you sleep.
