Despite everything that has happened to you in this life, including everything that you THINK you did wrong, you survived it all. Take that in and be with it. You are a survivor! Remember that truth when times feel difficult. Know that you are more than a survivor, that you can come out on the other side and thrive.
You are still here to talk about every event, at least the ones you remember. Just how many do you remember anyway? I raise this question because I guarantee that you have forgotten many more difficult times than you remember. There is value in noticing this: they are gone from your present experience and no longer disturb your state. What has power over you right now that you can see or feel in your life?
Notice that everything in personhood comes and goes. That includes the good, the bad, and yes, even what you thought was insurmountable.
The mind may keep ruminating over an issue, and I would ask, is this something that needs your attention or not? It does not matter if it happened five minutes or five decades ago, because once you identify with it in the present, it has the same power to distract you and change your state.
How much of your time is spent thinking about unnecessary things while overlooking what is necessary? You have a choice in these moments to breakdown or breakthrough! Which will you choose?
How many of your challenges can you look back at and see that they taught you something valuable? That the experience empowered you and put your life on a completely different trajectory for the better? If this did not happen, then look to see if you have an unresolved issue, or perhaps you are continuing to ruminate over something that is no longer an issue, and you need to let it go.
I repeat, know you are a powerful person. Recognize that you are a survivor, but you are more than that. Please remember that no matter what is happening in your life or how you feel about it today, it will shift, it will change, because nothing in your life of personhood lasts forever.
