I believe much of life, is a test.
I found, when I was out and about, way to much, I saw things, like happy couples, cuddling etc, while I am single and alone. And these sorts of things, depressed me.
So I learnt to stay in my house more, and work on my garden.
Flowers, especially pretty little ones, give me a lift, so I grew a lot of flowers in a nursery, with an automatic watering system I made.
I made a lovely garden patio, with a table, chairs, and a shade cloth, over the top. And I grew a creeper, around it. With a flower garden, and it looks gorgeous!
My feelings, lent on deaf ears, and it seemed nobody cares, so I set out on controlling my mind.
I worked out, that thoughts, lead to feelings, so I worked out, to stop my thinking process, to stop feeling, so I wouldn't suffer.
So now I, sit in a chair, meditate, and when I feel low, I do Chi Kung exercises, and cancel my thoughts, until the sadness spell goes away.
I remember, some of my darkest moments, nothing went right, so I imagined myself, in a dark pit, looking up, trying to find some light, (in my imagination), as I continued, my faith grew, and I could see light, like an angel, coming down to me. Making me feel better.
The Chinese, know about Qi.
It is energy.
I found, that when I am feeling low. I have an imbalance of Qi flow, in my body.
It is when I feel tired, low, and yet, cannot sleep.
Now I do a Chi Kung exercise, called lifting the sky.
It balances my energy system, and makes me feel cool in the head, and awake, and happier.
Chi, is Qi, just different spelling.
