Confusion

What do you do if your angry because your lonely but you have a wife and kids. But they say they don't come around because your angry and bitter all the time. But my anger turns to them for letting me fell alone. When at first I was angry with my parents, my job, and my addiction. Because of this anger my family started distancing thierselves from me. They don't know when I might explode over something they say so they stop saying anything at all. They don't know what my attitude is like at any given time so they are fearful to approach me with anything at all. They are scared of me and it makes me fell like a piece of shit.
