I can't do anything detox or rehab if I can't get off the lounge.
Sounds to me like all the more reason you need professional detox and then rehab, Sweetichick.
Admitting this problem is beyond your capabilities to fix could be the key to long term success.
You must want a different way of life than this - let your actions kickoff that change that you need
If you're having trouble getting around or taking care of yourself, you need to see your Doctor, or any doctor, and tell him/her the extent of the problem.
If you can't drive anywhere, and you can't get or afford a taxi or Uber, you can either google a home visit Doctor ( they bulk bill) or ring an ambulance to the ER?
