I don't know if this is due to casuality or causality but just now that I realized of my dependence issues, I was told about dependency in a course in my school.
The speaker named Covey. He was a personal coach.
He has a book that you can download in PDF for free that is called "The seven habits".
I can't still give you many light about the topic bc I still haven't read the book and bc in the course we have only seen the first three first habits for now.

Covey's main aim with this book is trying to guide people from a situation of dependency to an independency situation and then to an interdependency through the practise of the seven habits.
I know that it sounds very conductual but I think it's worthy a try.

What I know for now is that the first three habits that are suppoused to lead you to an independency are the following:

Habit 1: Being proactive, that is, I take my own decissions and I am responsible for them. Noone else. So, I choose how I want to be.
When I recive a stimulus, I decide how I am going to react. So, it's worthy to take a period to think between the stimulus and the answer.
For example, if I greet someone in the morning and this person doesn't greet me. I can think many things about that fact. I can choose being sad or feeling bad but the true is that we can't control other people's actions. I did what it's in me, greeting that person.

Habit:2 Having a goal: I live for a purpose.
It's important that you have a purpose in mind, it's the only way you are going to force yourself to get it.
For example, in my role as a teacher, my purpose is to make happy my kids in order to motivate them towards learning.

Habit:3 Establish priorities, that is, it doesn't consist on doing urgent things first but the important ones for me.
If I'm with my partner and the telephone rings, I choose the important one.

I hope I haven't bother you a lot, well, anyway, you and only you have the choice to stop reading my thread or go on reading.
