The leash: A reflection about a healthier Life

Last Sunday I had a very vivid picture of what it means to have an unhealthy relation to someone else's emotions.
It all started with a nice walk with my dog, Charles. We walked near my house, which is perched at the top of a hill. Some dogs came along and attempted to claim the front of our house as their territory. This wasn't something Charlie would allow. I shooed the dogs away and as they left, Charlie ran after them with all his might. The strength of a well-fed 1-year-old lab took me extremely quickly down the hill trying to stay on my feet. Soon enough the inevitable happened. I fell flat on my face in a mixture of concrete and dirt. I know it was the latter as well because some of it was on my mouth and nose.
I'm happy to say my bruises are no longer dark purple and it's a miracle nothing was broken or sprained. Yet, there was a question that made me think, "Why didn't you let go of him?" my sister asked. "Oh, I did! Once I was on the floor!", I responded at first. But then I felt a little glimpse of realization. Aren't my relationships with people sometimes that way? If my loved one is sad, and if I choose to attach an unhealthy emotional tie between me and him or her, my spirits will come tumbling down, no matter how great of a day I was having. Similarly, it can happen with happiness, and fear, and jealousy and all kinds of emotions.
The problem is that I let others guide my emotions, when I should be in charge. Just like with Charles, I was supposed to be in charge!
It's a weird phenomenon I'm still learning about but I know there are healthy and unhealthy responses that we can have to others' emotions. And it's tricky for me to get rid of some of these habits. Yet, I've taken it to Jesus and asked for his help and I can say He has been working!
For instance, if X is having a terrible day and chooses to look at the negative side of everything, before I would say, "Poor X! He's in a bad mood again." Finding out why was my mission, and then I would try so hard to revert X's mood. This wouldn't work most of the time of course, and if it did, it was short-lived. And the situation with X would continue, which would sadden me and make me unhappy for days until magically X had a happier day cause he finally decided to look at the bright side of life. This is taxing. Not the way I want to live.
Now, when X is having a bad day I'm not happy for it, cause I love X. But I know that X has a choice: to get himself out of the pit. He knows I'm here if he needs me, but if he doesn't want to come that's his decision. I'll still pray for X. Yet I'll be having a merry day because I choose to. I might be saddened that X doesn't want to join me, but my joy cannot be lost because of X. The joy of living is much too precious to tie it to the emotions of a mortal which I have no control over. I know I have to be mature enough to accept that every person makes decisions and I cannot make them for them. They have a choice and I have my own.
And the choice I have to consciously make every moment is to tie my joy to Jesus, and not anything of this world, including people.
