What Is a Good, Reputable Drug Rehab Center That Isn’t Insanely Expensive?

I have no insurance and no job. I am an adult but my Mom is using part of her retirement savings to send me to rehab so I want to get the most out of it that I can. I want to go somewhere nice with staff that is VERY CARING. It is also crucial that they have a lot of activities other than just meetings. I’m planning on going 90 days as the usual 28 days just doesnt’ seem long enough. I’m very scared of going because I’m afraid of detoxing, any advice? It would be nice to go somewhere very preety and relaxing as well!
