The Pain and Chronic Fatigue is Totally Overwhelming Me

I've been suffering from fatigue big time, since we got home from our holiday in Dubai. But, as other friends who went with us were also suffering from it, I thought it was just jet-lag. Now, a week on it's much worse whereas everyone else is back to normal. When I returned from our holiday I also decided to cut down on some of my medications as I felt I had rather over indulged in them while away. But, whereas I thought my pain would not be as bad now that I am home, it is actually worse. So, now I'm in what you might call a 'stale mate' situation. Do I go back down the route of increasing my medication to the max or not? Is it the over indulgence of them that has left me feeling so tired? Could all my symptoms be because my liver has been overwhelmed with what it has had to deal with over the last few weeks and possibly a few weeks before ? I'm normally such a positive person and just take each day as it comes but I have been finding myself thinking, 'what if I'm going to have another bad day tomorrow, as bad as today' instead of my usual, 'it will pass'. I've written on numerous occasions on pacing yourself and positive thoughts so I should not be the one suffering from this really, but at the moment I just can't seem to snap myself out of it. I think part of it has been that I have been covering my pain and fatigue with little lies and excuses as to why I am not having such a good day, but I think this has been building up for quite some time. I should have driven home from my Auntie's 90th birthday lunch yesterday but I knew I would not be able to keep my eyes open. So how come after sleeping for an hour in the car on the way home, then another hour and a half when I got home and most of this afternoon do I feel like I feel? I guess perseverance and some good mantras of positiveness might help. Apologies for burdening you all with my lowness, but sometimes it helps to write things down.
