Dear Welcome to HCM We understand your concerns I went through your details. I can understand your emotions. I don t think you are depressed, but I can see you are irritated and frustrated. You should be able to distinguish between disappointment and depression. Disappointment also brings on symptoms identical to depression but they are short lived. Anger and aggression are emotions. Anger comes when you become irritated. Irritation happens when you don t like something, or when something is repeated. As anger is an emotion, it should be vent out. You should be able to throw anger out instead of controlling it. But more perfect will be, know the frustrating situations and stop being emotional. If practiced properly, you will not get irritated at those circumstances at all. Those techniques are much easier to understand. You may contact a life coach or psychologist for further directions or therapy. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
