Why can't I stop obsessing about the negative in my life and instead focus on the positive?

It might be hard because for a lot of people, the negative things impact us on somewhat of a deeper level than the positive things. For instance, let's say you are hungry and I give you an apple. You're thankful and happy that I tried to help put an end to your hunger. But let's say midway through your apple I throw an orange at you. Suddenly it doesn't matter that I tried to help your hunger, but it impacted you on a physical and emotional level that I threw an orange at you (very loose example, mind you, but it still fits). Perhaps try to make a list of the negative and positive things you have in life and compare the two lists. Then when you're ready, maybe you could try and reflect on how the positives may/could outweigh the negatives.

Take a step back from all those negative influences and feelings in your life, and focus on what makes you happy, no matter how small, happiness can do wonders.

To stop focusing on negative parts of life and focus more on positive side and by altering your mindset every time you try something new even if it doesn't go well at least you have a positive thought or write down 5 things you are glad you took the risks for.

There's a glass, it contains half water and half air, then if i ask you how do you describe the glass then you should be able to say that its half filled with water but not its half-empty. In this way if you see the world in a positive way it makes you feel better..

Because being optimistic means being hopeful. And sometimes, hoping for something that might never happen will probably hurt more than admitting the negative.

It is because that we get so caught up in the past that we think it will affect the future. Just live the moment.

Because you had so much happen that was bad. You just assume negative things are going to happen....

Our state of mind is affected by what we perceive our future to be or what we want our future to be. This is affected by those we surround ourselves with, what they tell us about themselves/ ourselves and what we believe to be true about ourselves.

I always think that there's nothing poutine about my life so I constantly start thinking about the horrible things and it fills up my head

Hey its alrightt. A normal human gets over 10,000 thoughts a day. And i believe, All of us get hit by negative ones too. the difference is only in the reaction. The people who dont make a big deal out of em, simply..let them be, own em and not fight, have no probs with obsession
