I really feel irritated when something is not done my way and the peace in my family gets disrupted. How do I control this obsessive behavior?

You have to let go of things. Try to ignore things because your nature will affect you the most in a negative way. And if I tell you that you will have wrinkles on your face and look old much before than you actually would just because of getting irritated often, I am sure you would not ask for any other idea as how to control it. ;) But, yes, when you get irritable over petty things or big things, it first of all comes on our face and if we keep on doing the same thing the expression start leaving its mark on the face. It had started happening to me just till last month. I used to get so angry and irritable over the things that kids would be doing. I was always screaming or frowning about the mess that kids would make or if they didn't do things according to how I wanted. And it happened so that when I used to see myself in the mirror, I would see lines forming over my forehead and I felt end of my lips drooping. I don't know, perhaps I started overthinking that my irritable behaviour was affecting my face, but I think that helped me to control my behaviour. I mean, looking good is one of my priorities. :) So, the feeling that I might be losing my charm worked for me. You can try meditation and yoga. It will relax your mind and since you are aware of your problem, it will be easier for you to deal with it. You can also involve yourself in some hobby. It will keep you busy and you will get a new perspective of dealing with things and will help.
