I'm sorry for you. you obviously gained way to much weight which the reason for your back problems im guessing? It sounds like being overweight is the reason for all your problems. THC stays in fat cells and being 5'4 215 means you have plenty of storage. im a 6' tall male who weighs 190. because your so inactive you have no muscle to help support your back while it holds up all that fat once in a while, when you decide to stand up....i understand that you have back pain now and its to late to go back in time and work out and keep in shape so that your spinal disc wouldnt rupture under so much weight....but you should be able to stay on a diet without junk food! i can't believe that you didnt have the motivation to stay on the damn diet after all that you have been through, that blows my mind. now you have another chemical addiction to junk food that you must get over...everytime you eat junk food your brain releases a chemical that brings you pleasure. if you dont get over this and get back on a diet so that you can get to a weight that will allow you to do minimal excercising and self therapy then you aree in serious trouble. your looking at heart failure lady. do you really want someone to find you dead in a chair with a bag of chips on your stomach? and have everyone watch as 4 men load you into a body bag? get it together women....sorry for the tough love...get bettter
