I'm sorry you're not doing well. Could you afford to do a hair test through ARL and see what's going on now? I test through them and am a slow oxidizer. I have been taking calcium daily but also with other supplements that my practitioner recommends. It's always risky to just use one.
Even if you can't afford the whole supplement program, working with a good practitioner and using the few you hopefully can afford could bring about better health. My practitioner is great and I would be glad to recommend him if you want his contact info. He has been trained under Dr. Larry Wilson. Personally, I find those to be the best.
