I have what meditators refer to as “monkey mind.” My mind never shuts off and that greatly contributes to my insomnia. I try to read this quote every night as a way to rid myself of the days’ highs, lows and in-betweens. Perhaps it will help you. Blessings.
finish each day and be done with it. you have done what you could. some blunders and absurdities have crept in; forget them as soon as you can. tomorrow is a new day. you shall begin it serenely and with too high a spirit to be encumbered with your old nonsense. ~emerson
