Reddit mentions of 8 Minute Meditation Expanded: Quiet Your Mind. Change Your Life.

"Power of Habit" is good for learning how to form habits/reading some anecdotes. Very helpful and illuminating.

Here's a good beginners meditation book that will give you a schedule/few different kinds of meditation to try. Makes it very easy: https://www.amazon.com/Minute-Meditation-Expanded-Quiet-Change/dp/0399173420

Also, if you're more into audio, it might help to try thinking about mindfulness in a different way. For that, I can't recommend Ellen Langer's work on mindfulness enough. This interview on the On Being podcast really helped me think differently. I found her views on life to be contagious: https://www.onbeing.org/programs/ellen-langer-science-of-mindlessness-and-mindfulness/

Last but not least, have you read/listened to Thict Nhat Hanh? This is a very good book. Very good insight on self care and self love, not to mention a fantastic explanation on how you can learn to meditation by practicing throughout the day: https://www.amazon.com/You-Are-Here-Discovering-Present/dp/1590308387

I also highly recommend trying to jump into a class at some point - yoga or meditation, either way. It's a change of scenery and will push you in different ways mentally, but also help you see that the experience of consciousness is always your own.

Hope that helps. Keep trying and you'll find something that works.

A mindfulness practice pairs beautifully with stoicism.

Check out 8 Minute Meditation by Victor Davich. The (originally Bhudish) practice of mindfulness is focused on being aware and engaged with our own thoughts. The book teaches several different (agnostic) forms of mindfulness and is a great first step or refresher on Bhudist-style mindfulness meditation.

I'm not an expert on hormonal imbalances nor CBT. I thus think people other than me have better clue. But, if not, you might try allowing the mood to exist for a while until you feel calm. You might practice this so that you get calm easier and quicker.

Here's a reference that helped me to practice just that:

I recommend you reading the customer reviews.

I know I'm commenting on an oldish post, but if you're still looking for meditation resources, I highly recommend 8 Minute Meditation: https://www.amazon.com/Minute-Meditation-Expanded-Quiet-Change/dp/0399173420/ref=sr_1_3?ie=UTF8&qid=1536287257&sr=8-3&

What I love about this book is it makes meditation HIGHLY approachable, even for people like you who have insanely busy lives, and walks you through many of the different kinds of meditation that are out there. Might be worth taking a look.
