At some point you need to evaluate whether the fear of failing and / or talking to strangers is worse than the pain of living with your mother. I doubt lazy would be a reason to stay in the situation you're in. It sounds more like learned helplessness. Which is totally fixable if you are willing to address it. You are not lazy, trapped, or any of the things you think you are. You are going to need to let go of the thoughts and behaviors that put you into that trapped helpless victim box inside your head.
