Dear
Welcome to HCM
We understand your concerns
I went through your details. I suggest you not to worry much. Anger always comes due to frustrations in life. Frustrations are normal with everyone. 
People learn to ignore frustrations when they get experienced. Do you get angry to circumstances outside your home as you get angry at your house? Your office, bus stand, railway station, neighbors etc. If yes, you might need to get evaluated for anger issues. If NO, just understand and compare the two situations and you can be better yourself.
I sincerely suggest that you are victim of your own negative thinking. You cannot term your current state of mind as clinical 
depression. Rather, this is just disappointment. Disappointment which arises out of unforeseen life events do bring such symptoms like sadness, irritation, anger, 
lethargy, lack of interest, 
lack of appetite etc. Please understand this fact and make sure to introspect. Talking to your friends, out door activities and being creative should give you relief. Find the reason for your disappointment and 
consult a psychologist if need be. 
Psychotherapy techniques should suit your requirement. If you require more of my help in this aspect, Please post a direct question to me in this URL. http://goo.gl/aYW2pR. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques.
Hope this answers your query. Available for further clarifications.
Good luck.
