Above all, dream your own dreams... The world is wrong about a lot of things -- why not rethink how you feel about you?
Many Castles, different paths... You'll find your own way to living happily, healthfully & sleeping wellfully.
Your need darkness to balance not only daylight but to mitigate gadget fatigue! Computers, phones, TVs, tablets all interrupt the slow process of dusk to twilight to night required to rest and awaken fully refreshed. No matter your circadian drumbeat, get some darkness -- or light -- if needed!
You may have spent years forgetting how to sleep naturally, so, take your time as you rediscover & reconnect.
Sleep restores balance, but decompression comes first. If you're anxious, worried, or pushing you aren't resting - it's just more stimulation. Recognize when you're trying too hard, then give yourself the gift of letting go...
A seed cannot grow itself, nor can you. You have an entire universe helping you to grow... Faith is accepting this fact with Love. Know all is working out: Faith is not blind but doing your part and letting something greater help you with the rest! ;)
Now, go forth and sleep well.
