Hi everyone, I'd like to join please 
I've had GAD for forever and periods of depression on and off for 20+ years.
Having both is torture.
I used to self medicate with alcohol (used daily as an 'anaesthetic' - bad idea) but I don't drink anymore and I feel a whole lot better for that. So if you drink to feel better, maybe think about having a break from that as it actually ends up exacerbating both depression and anxiety.
I'm on citalopram 30mg. I was on 10mg to start with but dr increased it last summer due to some acute stress giving me bad symptoms. I'm hoping I can reduce the dose in the future with some lifestyle changes.
I've also started taking some supplements to target any missing ingredients from my diet/brain. I take omega oils, multi vits, extra vit B complex and magnesium. I also take L-theanine which I do find makes me feel noticeably more relaxed throughout the day. And I just ordered some tryptophan which is the precursor to serotonin.
I have similar symptoms to you mumsy especially terrible decision making and not wanting to eat at times. However, my DP pointed out to me a while ago that I feel worse when I don't eat, and almost immediately better with fuel on board. So I do try to eat when I'm feeling particularly anxious, even though often the thought alone makes me gag. I keep protein or breakfast milkshakes in the fridge, or yoghurt drinks that I can stomach better than solid food, and they help get the ball rolling.
Thanks for reading, it's great to have a thread for this - thanks OP
