I wasn't kicked out. I joined the Navy and left. At some point, it is the responsibility of the child to end the childhood and become a self-sufficient adult.
I was not meaning to judge, even though I am sure it came across as that. Do you have a place to stay? If not find a shelter or a friend. If you are overwhelmed, just clear your thoughts and get down to basics. Find the things that are required, shelter, food and clothing. Once your secure those things, even if temporarily, work on the other things.
I had enough ambition, to start my own life, at 18 years old, and get out of their house, under my own terms. Some of it was respect for my parents; some of it my maturity, instilled by my rearing. No parent should have the burdon, of supporting a healthy, adult offspring.
