I'm sorry to hear you are feeling so flat. I had a quick read of your thread. You have been through the mill over the past few months. Did you feel better after the treatment for the stomach infection? Are you still following the diet?
I can relate as I am dealing with similar chronic problems including pain. It is debilitating, and like MI, it is invisible to others and that can be so frustrating. At the moment, I have given up on medical appts. They are so stressful, and I can't afford it anymore, anyway. I find it is easier to ignore it. Probably not healthy, but I was doing the roundabout like you, and not getting any relief anyway, so I don't feel any worse off now. Not being very positive, sorry, but I guess that is how I cope. I will probably go back again eventually, when I absolutely have to, but until then I just deal with it all, by not to thinking about it.
I do find that vitamins, like D, B, C and magnesium and Zinc do help me have more energy. I have also started Probiotics. There is a lot of info on brain-gut health interaction. It looks promising. It can't hurt, especially after all the antibiotics we swallow. They have definitely increased my appetite which was nonexistent before, so I know they are doing something I need. I don't need the weight back that I've lost, so Im hoping they help with metabolism as well. So far, so good.
For me, sometimes it is motivation that is missing. I might want to do things, but really just don't want to, so don't. Well, it make sense to me. I just can't be bothered atm. Even if I start something, I often give up before finishing it. So I usually end up doing things in stages. Most things eventually get done that way, and even if they are half done, it is better than nothing. Who WANTS to do the dishes or do the vacuuming anyway. A friend once said to me 'at our funeral, no one is going to say, wow her house was so clean', so that stuff is pretty thankless anyway. Maybe tackling things in stages is something you could try.
Sorry it's not the most positive post, I'm sure you'll understand. I do hope you start feeling better again soon. Perhaps spend some time with the grandkids, try and absorb some of their energy...where do they get it? I'm sure you'd feel a bit better after that anyway.
Warmest wishes for you, Lee x
