Way to go! You made the first step toward a new life!
It will be hard, but you can always post here or just read and learn, which is what I do, when the going gets tough.
You will be fine - contact your family. I would imagine they will be happy to hear from you and hopefully be a source of support.
See a therapist if you think you need one. Keep busy, know that the hard moments won't last forever, and know that there are scads, and I mean scads! of us out there who have gone thru the same feelings and emerged better people for it.
The last thing I would say, and not everyone will agree with me, is to get in touch with your Higher Power, whoever or whatever that may be. That alone has helped me more than anything.
Take care.
