How do I stop thinking about death?

i think about all the people who will miss me and who will be hurt by my death , i think about all my dreams and the things i have not done yet

You have to distract yourself first. The longer you think of cynical thoughts like this, the more prone you are to continue this mentality. In terms of coping, distracting yourself will help you minimize and deal with any stress related to these thoughts. You can distract yourself with literally anything (movies, books, exercising, etc.). Once you start doing something, and allow yourself to be immersed in that activity, your negative thoughts will eventually pass. The next step to long-term elimination of these thought would be to change your mindset. You have to actively stop yourself from following this train of thought. Try catching yourself when you start thinking about death, and then immediately change it to a positive thought. However, also be careful not to avoid this fear of death (if you have one) entirely. Sorry to be frank, but death is a reality, and is a truth that will need to be dealt with eventually, but do it in your own time. I hope one or more of these steps helps you out!

Death is an odd subject. We must realize that we each owe a death, and that none of us are being singled out. However, we cannot use the finite amount of time we have worrying about something inevitable that we are powerless to change. If you do find yourself thinking of your own mortality, consider the billions of years before you were born. Were you in any discomfort? Conversely, would you truly want to live forever?

If you are obsessed with death you're merely existing . Do you want to exist or be living ? If you're answer is the latter (living). You have to start focusing on your purpose,things you desire and improving your intellect. Focus on self-improvement to stop thinking about death.

Start doing things for yourself, not for everyone else. When you do things to please others, it becomes a very rocky life indeed. If that person or people that you're trying to impress end up turning on you for example, you'll end up blaming yourself and you'll have no excuses for staying alive. I've heard before that clinging onto things to stay alive is wrong and it is depending on what you're clinging onto. Cling to yourself; tell yourself that you will make your life better for you. Think about everything that you've accomplished, give yourself a sense of achievement. Never give up! I started clinging onto myself and it's made me a lot better. Every person I meet, even the person behind the checkout, I always say just before I leave "Hope you have a wonderful day" and the surprised look on their faces is fabulous. Even better if you say it on the phone to a random stranger like when I've had to call up my phone provider, they usually stammer and then say you too. Haha. It's the thought that counts and that simple small act of kindness, is all it can take to make your day and their day worth while. You may never truly stop thinking about death but not feeling the need to do it 24/7 is much better than the alternative. I hope you feel better soon. When in doubt, keep smiling.

Some time in our life, we might question our purpose. When we can't find it, we go to the thought of being worthless and death itself. But look back at yourself. Look back at the people you've touched with your life. We are born for a purpose and to live. Nothing could have been the same. If you want to stop thinking of death, then go and think of life. On how wonderful it is and how precious it is. Think of it as a treasure that's too special to waste.

You can stop thinking about death by not thinking about it. Whenever the thought comes to your mind, try to divert your thinking.

Embrace it. A perfect way of doing it is by realizing how the universe works. The minute you were born, your soul was imparted with a physical body through which it could experience it's being. Every thing that you experience and want to experience is,in fact, desired by your soul. It doesn't command you to do anything; that's the job of your mind. It merely talks to you through how you feel about a person or a particular situation-hence the saying "feelings are the language of soul".

Talk to someone about it. Go out and do something active. Play sports. Go to the store. Do yard work. When you stay active you feel happier and healthier mentally and physically.
