Holding Guilt?

It used to be fashionable to say "my friend" instead of coming clean and being up-front with the truth. It doesn't matter to me, I'm just some anonymous therapist out in virtual space. But you're the one who is writing, and if it was your "friend" who truly had the problem, then it would behove "her" to call Aetna® and ask these questions of someone who would actually have an answer. I don't work for that company, I'm not omniscient, I can't answer your insurance questions. BUT, I can read someone trying to avoid dealing with reality, which to me spells a-d-d-i-c-t. So, if it's your "friend" who is having issues with rehab - "she" needs to ask herself how she got into rehab in the first place, because if someone finds themselves in rehab, it's not for nothing! Someone has had to become dysfunctional in the extreme, arrested, involuntarily committed, or mandated by the court. Rehab isn't like, "Oh, should I take my holiday in Sandals®, Jamaica, or should I check myself into rehab?" Talk about "bullshit!" 

Sorry if this sounds harsh, but it's time for your "friend" to learn some coping skills after "she" re-sensitizes her doped up nervous system, and that is precisely what rehab is good for. If "she" is there, it's for a real reason, and "she" may as well get something good out of the experience, as unpleasant as being drug-free might be for the time being. If you're asking a therapist, good, but you're asking the wrong questions. It's time to cop some courage and submit to some deep therapy, maybe hypnotherapy (my specialty because it's brief and less painful, plus hypnosis feels good). Otherwise, unless your "friend" wants to get to the bottom of the trauma that's created a slave, and unless she wants to be free, "her" life is going to be short and shitty to boot (no hitting-up pun intended).
