I've been knackered for months, feeling squishy-flat, no interest in sex, not getting enjoyment from anything and, recently, have gone off food (still eating the same amount but not deriving any pleasure from it). Don't even feel like exercising and I love exercising.
I've spent months thinking that it was probably a thyroid medication problem. However, when the death-thoughts started turning up I thought it was probably time to see my GP again; she's a psychiatric specialist.
It would appear that my antidepressant has stopped working (as my thyroid med levels are now good) and I'm being kept afloat by lithium. The problem I have is trying to pin down which of the blasted neurotransmitters I'm low in (my money's on noradrenaline and dopamine) and trying to find a new AD which doesn't have major weight gain and blood glucose control problems associated with it as I'm already prediabetic. And which I can have a glass of wine on without having to worry about passing out.
I have seen many posts on this forum which suggest that mental health problems (particularly depression) are caused by poor thyroid function. But I'm here to say that sometimes, it really ISN'T all about the thyroid.
