I have found the following not-quite mantras to be of enormous benefit in times of need, when I have been mired at the lower end of the emotional scale.  I  hope you find them useful too.  (Some of them may be slightly paraphrased from the original quotations.)

“May I meet this moment with ease and grace and an undefended heart.”
~Sylvia Boorstein

“Sweetheart, you’re having a hard time right now.  We’ll figure it out as we go.   ~ Sylvia Boorstein

“Out of this situation only good will come.  I see this situation resolved for the highest good of all concerned. All is well and I am safe.” ~Louise Hay.

“The Universe knows me and the Universe adores me.
If you will allow it, you will feel the love that flows to you and through
you.
You are always seen, always understood and always loved.”
~Abraham-Hicks

“I’m sorry
Please forgive me
Thank you
I love you”   ~Ho’oponopono, Dr. Len via Joe Vitale

“I allow the light to dissolve away all fears, worries and concerns related to money, security and safety. I know that I am perfectly protected in all ways and that all of my needs are met and provided for at every moment.” ~Doreen Virtue

“Is love available even here?”  ~Mark Silver

“I will be gentle with myself
I will be tender with my heart”

“At this moment, I have everything I need, and I am so very grateful.~(Origin unknown to me,  quoted by Elyse Hope Killoran)

If times are difficult for you, I hope these sayings help soothe your heart.
