Hi again Mat52
I don't for a minute think you may have Addison's but there's a chance your adrenals have been depleted by some of the long term medications you've been on (as well as chronic illness). I'm no expert but I think Methotrexate for one can do that. Also have you been using Zopiclone long term - It doesn't affect the adrenals (just reread the data sheet a couple of days ago as I've used it sporadically) but it is not recommended for use more than 4 wks and can have side effects.
Here's a link to the NZ Medsafe website if you want to check it out:

Your GP could order a serum cortisol test to see if you're low. Usually done at 8am with fasting. Sodium & Potassium balance is also another indicator of adrenal insufficiency but usually an imbalance won't show on regular testing until someone is into crisis. Hope this is useful.
