But where are you getting with it? Is it helping or just spiking anxiety? There's a million rabbit holes to fall into which can make things a whole lot worse - I've seen it over and over again...I'm definitely an advocate of taking our wellbeing into our own hands though man and not always 'outsourcing' it, but we need to know what we are dealing with first
Invitation is to wait until results come (can;t be long for sugar-levels?), and go from there. At the very least by then you will be able to rule a few things out, or they may even pinpoint your problem. It could be all manner of things, shit's complex! You could take some pre-emptive measures like cutting your sugars/bad carbs down etc, so at least you'll feel like you are doing something potentially helpful (you seem good at that anyway tbh)
I'm sure you're aware, but your adrenals could be quite fried from the heavy stiumulant use. This can heal, but we need to be aware that keeping anxiety down is really a must, and in and of itself will be much more helpful for your wellbeing than dark speculation (no judgement bro...been there and still am on/off)
