Hello; For some folks the best parts of their lives turns out to be the teen years. Things can and often do take a down turn when we reach the age of majority. I started mostly being on my own at 18 and was completely on my own by 19 back in 1965-66.
Things have changed here in the USA it seems. Now kids must stay at home until age 26. At least the parents can keep them on their health insurance until that age so far. This has become a big deal in the current health insurance debates. I did not get any form of health insurance until I was 27 or 28. I had to take care of my own bills until then.
You might not wish away this time of life too strongly.
I too was on my own 18/19, back in 2006ish. Been on my own since.
