Everyone sees a different you. They see someone who goes to work, talks to the neighbours, makes people laugh or turns up at family gatherings. They don't see what happens when the drinking starts. They don't know what it feels like to be scared and ashamed and desperate.
You become careful about what you tell people. You hide how bad things are because you are embarrassed, because you don't want people judging them or because explaining the whole thing feels impossible. Even the people who know something is wrong don't really know what it is like to live with it.
After a while, your world gets smaller. You carry things you don't talk about and deal with situations nobody else sees.
You need practical help for you and your family and social and emotional support from people who understand your situation.
