I can imagine. And pardon me for being so frank, but not only is it hard work, it is not likely to work without some other plan in place.
In addition, just thinking about a way is not enough, action must be taken. The good thing about rehab is that the action is taken for you if you are so overwhelmed and beat down by the battle. You get there and they take care of you and then show you the way.
Why don't you call a few places today? Some basic questions to ask:
1. When can you admit me?
2. Do you provide transportation or do I need to get there on my own?
3. What are the options for a payment plan?
