I have trouble with logical thinking, can't do simple mental maths sometimes and I don't seem to be able to realise my mistakes in time.i was wondering if anxiety and its symptoms could be influenced by what I'm eating? I am overweight and I don't eat regularly...i wake up at night sometimes, hungry like I haven't eaten in a month.. I have cravings or I forget to eat because I'm not hungry all day... Could anxiety symptoms be controlled by what we eat and thus lack of concentration be corrected?
