We've all had to deal with disappointment at some point in our lives - maybe we didn't get the job we wanted or a relationship that we hoped would have worked out fell apart. Occupying space in the gap between what we wanted that has not come to fruition and what will eventually manifest can be difficult.
The way I like to deal with such experiences is to create a "10 Reasons Why" list. So, if I don't get something I really want for myself, I try to think of the blessings in the situation and jot them all down. I then keep this list close by me - I keep copies of it in my purse, at work, and at home and read it whenever I find myself going back into the feeling of disappointment and the thought of "why didn't this work out!"
In coming up with 10 reasons, I suggest focusing on the things that weren't optimal about the situation. For example, if it was a job that you wanted that didn't work out, there could have been some downsides to that particular position - maybe you would have had to move to a location you didn't want to be in, or maybe the compensation wasn't as a high you would have liked it to be or maybe you would have had to trade off other aspects of your life that were important to you. You basically want to create a list of all the negatives in the situation and then thank the universe for the blessing of not having to deal with them. Then you have to keep the faith that the right thing will come along in divine timing - which I know, is this super annoying force but it always operates at the best time and in your higher good. So it's annoyingly smart and you just have to trust that :). Also trust that if something is not happening for you now, it's because there's something else you are meant to be focusing on and learning from. Energy healing can be a powerful tool in helping you attain this insight and removing any energetic blockages that might be tampering with achieving your desires.
By doing this exercise, you will be able to focus on gratitude as opposed to the feeling of lack or victimization and keep centered in your faith that the universe is your co-conspirator in creating the best possible outcome for yourself. And then when what you want finally comes around, just say "thanks universe for having my back!"
I hope you'll try this exercise! :)
