Ya sister u require some calmness. Some people will like that only being innocents for them whatever we have done they will not have ability to understand. But for ur life he is important for u and also for ur son. Do u thought how ur son feels without his fathers love when u leave ur husband, and what will be the effect of ur angryness and fighting with ur husband will cause depression on his mind. I know u r struggling financially but u can c others which don’t have even one time food for there life. Everyone has problems in their life , every one cannot overcome from this untill they try their level best to solve them so just have faith in God and urself that u can overcome frm ur all problems. And u will do it soon, when u get angry then just remember ur son’s face and his future then u will get some calmness try it..
