Hello, Charles Darwin wrote, "If we expect to suffer, we are anxious; if we have no hope of relief, we despair.” These feelings are natural, but need to be kept in check, otherwise they become counterproductive. Easier said than done. Sometimes, I swear and cuss at my circumstances, cussing is an analgesic, it increases adrenaline and relieves pain. It's natural, cheap, and reasonably effective. I always try and think of the next thing I can look forward to, for instance, if I get up ealier than usual, I think about the pleasure of my next nap. If I am faigued, I think about sitting down and having a friendly cup of tea or a stout in the garden. Or particuarly for me, it's an evening with a book or my mug of Horlicks and sitting down to play a video game. Always looking forward to something to look forward to, despite the debilitating unpleasantness I feel mentally and physically most of the day. Personally for me, I chose anti-anxiety medication to see me through recovery. This choice was because my malaise was crippling to the point of me being almost bedridden for several months at the six month recovery mark when progress slowed down. I also augment this with natural methods to relax and calm, I dab lavendar oil on my pillow, I take a swig of dark rum to soothe my nerves if anxiety is acute, I listen to ambient music on a soft headphone headband, and use camomile cream. It's an artillary of mollification because I need as much bolstering comfort as I can tolerate.
Doctor's love the phrase 'see how it goes'. But hopefully you can find those things that might draw you out of despondency, and you do have hope so do not despair too much, although, I know it is difficult to keep these thoughts at bay. I try and make light of my circumstance to other people, such as saying to them that while other people run on a lithium battery, I'm charged with a Poundland double-a, or if someone is waiting for me to walk past them, I often tell them that they'll be waiting for a few hours.
I really hope you can wriggle out of these thoughts as much as possible. Anxiety is a tought nut to crack, but it is all in the mind, unfortunately for us, that's where most of our trouble is, so we have to be brave and persistent.
