Greetings Amari, read the forums, read them some more, then when you are finished, read them some more

There's a wealth of good reading here, and you won't regret any of the reading.
Post your thoughts, it is very helpful to hear that most of what plagues you is not something rare, most if not all of us have been there or are still there.
The ole saying it takes one to know one. Well there are no shortages of people here that are essentially you.
I'm glad family is cool with it. Regarding mother and finances, hey yer 21, you are your own responsibility anyway. HRT costs or payments on a car, it all comes under the heading of your own life now. As long as they are cool with you, that's the battle you want to win, everything else is just day to day routine eh. There's always going to be expenses in your life.
Just remember, you set the pace, but it isn't a short journey and it doesn't need to be a short one. There is a lot of things to cover and haste is not always a good thing. Don't be afraid to take a deep breathe and tell yourself, 'I am doing this, but I am doing it right, because anything worth doing is worth doing the correct way'.
