I’m at the point where tiredness is now a big priority for me - which is nice, because I remember when it didn’t even make the Top 10!
So, I don’t have an answer, but I’m going at it hard! I’m checking in and tracking throughout the day, and keeping a record of factors that are playing into it, like: time I took meds, exercise (type & duration), sleep (duration & quality), thoughts (see below!), diet, work stress levels…
I have a big issue with over-generalising. It seems to be one of my favourite types of cognitive distortion! And when I’m tired or stressed, my brain goes very quickly to “I can’t cope”, “I can’t do this”, etc etc. so, I’m working pretty hard on that as a bit of a side project.
When I’m doing my check-ins, throughout the day, I try and figure out where my thoughts and emotions are at, but also how my body is feeling. And for me, at the moment, there are periods of the day when I feel energised (after yoga, for example), and times where I very clearly feel tired because of something specific (like taking my meds at the wrong time).
I have also ruled out nutritional deficits (blood test, and sticking to the nutrition plan that my doc worked up with me).
Based on that, I’m thinking that what I’m experiencing is normal waxing and waning of tiredness, rather than low mood. Because despite the over-generalising that my brain loves doing, there are periods where my body is definitely fine, and periods where my body is energised, and when I’m tired, I’m usually able to identify an obvious cause.
Tldr: I don’t know the answer! I’ll be following this thread because this is totally relevant to me right now!
