HOW I CAN DEALING WITH ASTHMA DISEASE

Firstly, i'm just wanna share my experience of how can i dealing with asthma disease.

First time i recognize that i'm suffer from asthma disease is when i was in the elementary school, approximately i'm 8-9 years old. As i know i got this ill isn't because my dirty lifestyle but it inherited from my father.
In that time if my disease is turning on is because i'm in the wrong path that i'm eat non-healthy food for example like instant noodle, chips, fried foods, ice beverage, I feel tired, i overwhelmed about my activities that i can't handle, i'm in the cold temperature etc. If those things happened automatically i feel like short breathing, like asthma relapse. 

I go through a long period of this worse circumstance in 2-3 years, and one day i thought i have to go specialize doctor to consulting my disease, And surpisingly the doctor say that my disease never heal!. OMG i was so shocked! In my mind, it means that i have to deal with this disease for the rest of my life? I have to eat the medicine forever?

Oh noo, i have to search another way to dealing this!
Doctor just suggest me, to avoiding the things that caused my illness turn on just that!
From that i guess, what can i do? And then i searching for this disease, everything about that! from that i think nothing is impossible if we try to make it happened, and i began to searching what is asthma desease? what caused it? how to solve if it came to us? and i decided to buy some books about asthma, and i have preference from those books and i applied in my life

Definitely we have to avoiding the alergen, we have to eat healthy food, do more exercise especially swimming to train our breathing cycle, don't doing heavy activities, don't in the area that has cold temperature and many more. From those books i suggested to don't eat artifcial flavoured, coloured food especially yellow: tartrazine, fried food/ contains too much oil, or foods can caused cough or sore throat becuase those stuff can triggered narrow breathing

It's very heavy to doing that stuffs with do and dont's, moreover i'm still child sometimes i envy to see my friends feel free to buy "dirty snacks" Approximately 3-5 years i had been through this "therapy" and as long as my astma never ail again, exactly from my hard effort to discipline with myself and until now that "healthy lifestyle" is ingrained in my self, there are no useless effort if all is doing with good intention and consistency to reach the goals
