What can one do if they don't know how to live alone?
E.g. they don't know how to take care of themselves when alone and stay connected with people due to violently being ignored and avoided home, shown no warmth and consideration or respect as a human being, for example (plus other ugly behaviour). When your parent doesn't see you and it's like you don't exist.
So how can they live alone?

I was not taken care of at all.

In this case, I always just sleep until late afternoon, evening or all day, don't know how to talk to people or invite them out, feel lonely and often scared about all this. I just don't know what to do with my time. (This is the same if I live with more people but I feel relieved if someone “knows" about this issue.) Every day is the same. Everything depends on you which is frightening because you can live in a mess and no one will know. I feel unpleasant and like I can't take care of my basic needs. And I can end up alone for a long time.

What do you think about this? Any advice?
