@creative_writer yeah it sounds like there's a lot of compounding things, possibly all antagonising each other. Have you had much come to light from your medical supports? I imagine it would be quite interrelated with your mental health too ay.
It can be really hard to disentangle from things that our brains have accepted as 'fact' for so long. It can help I think to practice stepping back from one's own thoughts, becoming the observer. When a faulty belief rears up, you can focus not on the thought itself but on how it makes you feel. How your mind reacts to it. Focus on undermining the belief with alternate perspectives, finding evidence that dispels the power of the belief.
Is there any of those beliefs that you wanna chat about, unpack further here together?
