Sorry to hear about all of your health issues. What I would personally suggest is taking it one step at a time. addressing each issue separate and individually. I would not jump into anything drastic. First try going on a very clean raw organic diet for about 2 weeks. Slowly weed out the meds and see how you are doing. I would incorporate some very good whole food organic supplements (I recommend Garden of Life and New Chapter). First I would start with a good multi, I like the Garden of Life Raw line. I would then suggest the FYI from Garden of Life and this helps with Arthritis and rebuilding cartilage. I would also get Garden of Life super seed, which is a great fiber supplement to help cleanse and get your bowl healthy, you will also need a good Omega product and I recommend New Chapters Whole Mega. You should also take a good pro-biotic supplement to help rebuild good gut flora and bacteria, there are a lot of good ones just go to a whole foods store and ask the vitamin rep for one of the best. I think Depression has a lot to do with the body not being balanced, especially hormones. Also if you are using a lot of chemicals this is a big NO NO. This includes perfume, lotions, hair products, deodorants, bath soaps, household cleaning products, etc..this stuff gets into you system and really changes everything for the BAD. You will need to switch to all the good stuff that you find at the whole food stores, without all the harmful chemicals, this is a very very important step. After doing all of this and slowly adapting your body, rather than shocking it, I would then, once you are okay with being off the meds, start the MC. At the whole foods stores or really any bookstore you will find the books on the Mastercleanse. There is also the website which is http://therawfoodsite.com/mastercleanse.htm
Also please by all means you will definitely want to check out http://www.mercola.com
and subscribe to the free newsletters and check out previous news letter and videos, I believe you will get a lot of help from Dr. Mercola. But I would definitely do The Master Cleanse to rid your body off all the meds you took in the past. A lot of stuff stores in the tissues and a good cleanse is really the only way to get it out. I hope I have been a help for you, and good luck with everything. Please keep us informed on how you are doing. Also another thing, about the hair issues, if all else fails try taking 6,000mg of good MSM with 10mg of biotin and Jarrow formulas pepzin GI.
good luck and take care...Jamie
