If we feed our minds a never ending flood of negativity, then the only thing that will be coming back out is negativity / Garbage. It doesn't matter how we phrase it, if we're always putting ourselves down in our minds and with our friends and family, we will never be able to overcome depression. One way we can overcome this stream of negativity is to start a list.  Day 1, you write down something / anything you do well - no matter how small it might be. Then you begin to repeat the statement in your mind throughout the day at least once per hour. On the second day you write one more item on your "affirmations" list. You then repeat both items every hour or more all day. Day 3+++++ continue to repeat day 2 instructions forever. 

It sounds simplistic right now to think that even the very tiniest positive impact you have on another person, something that you do really well, something you do really well that benefits you and others,  can all add up to changing the narrative inside your mind. But it can and will. 

Don't tell anyone about this exercise until you have been working on it for a month. By day 30, you're feeding your mind 30 things that are positive, and that by itself is HUGE!  

I totally understand that you are skeptical about how this can possibly change your mindset and can even vhange you enough to back you out the ledge of suicide. I don't know you, but I do know that I have been in incredibly dark places, far more times than I will ever admit. But I have been able to walk myself back from the ledge many times through methods like this and this method.  Only you know where you're at right now, but I promise you this: no matter what you tell yourself about your family, coworkers, spouse,  partner, friends, etc. - I GUARANTEE YOU THAT THEY WILL NOT BE BETTER OFF WITH YOU GONE!!! Get that absolute bunk out of your mind permanently, because it is clouding your judgment with bad information!  I have been battling severe depression for over 3 decades due to unimaginable chronic pain that is about 9.75 out of 10 24/7/365. I am grateful for my faith, my wife  children, and other family & friends and unknowingly gave us the strength to get myself off the 'ledge'. The more I thought about those I love, the more I came to understand that the pain they experience because of my pain and how it impacts every aspect of my day, and I looking at how much pain you can see them experience when a family member dies  - I finally saw how much worse it is for them when it's suicide - because the will have guilt surrounding my suicide forever. It will tear them up running it through their mind over and over trying to find what they could have done, what signs they missed, and the list of ways that they will torment themselves is too long and devastating. 

I hope and pray that this very long post will help others through sharing my experiences. I don't wish anyone to have to deal with thoughts of suicide, but I hope that this will be the light at the other end of the tunnel of your despair and guide you to the path to happiness. It's possible, no matter where you are on the suicide path. I pray for you.
