First things first......
First, you know what you dont want, thats a good start.
Next, are you willing to do what it takes to gain financial/emotional independence?
Last...do it!
Good start, imho, is al-anon..first and foremost. You need to know how others have done what you want to do. They're there...go meet with them. Listen and learn. There are NO quick fix. Unless you win the lottery,you need to work, you cannot gain job skills that take months or years to obtain.
Wanting it is one thing, learning what steps you need to take is another, and the actual getting out there to do it is the last.
Get support, get knowledge to understand yourself better, and you will find a new way to live...........
