I really understand the way you're feeling.
I know you wanna ctb but, you might try to live alone enjoy some time at peace for a while before doing it.
I've lived alone for 8 years. It was the biggest challenge of my life and I worked lots so as to be able to rent whatever!!
However, last year I lost my freedom for 5 months because of my failed attempt and you can't imagine how much that sucked.
Now, I'm free again.
I hope you can live alone some day too! Just do your best to save some money and then rent a cheap place. It doesn't have to be an awesome apartment. Anything will work as long as you're alone and have peace.
Hugs and love,
Matt
