Here is one of the most inclusive lists of symptoms of anxiety I have come across:
Too much adrenaline in the body causes ALL the symptoms anxiety sufferers are so familiar with:
The typical changes in the heart rate associated with anxiety;
Body sensations like dry mouth and throat, trembling (like in shakey handwriting), sweating, flushing, chest pains and tightness in the chest, being unable to breathe properly;
Racing thoughts that spin out of control; paranoia and hallucinations;
Headaches (stress headaches, anxiety headaches), migraines;
Vision disturbances, dizzyness, inability to see things clearly or to interpret what is being seen correctly (like dyslexia or totally failing to make sense of numbers, maths, symbols, maps, etc.);
Digestive problems as digestion is shut down or reduced during adrenaline outbursts;
Eating problems such as sugar cravings (insulin reduces adrenaline in the blood), hunger pangs, and also loss of appetite on the other hand;
Hypervigilance or becoming overly sensitive to all sorts of sounds, sights, touches, tastes and smells;
Failure to be able to concentrate on the here-and-now, functional failures (performance anxiety) like clumsiness, erection problems, "blocks" (to writing, public speaking, social skills, learning etc. etc), forgetfulness;
Inability to focus on others, making good connections with others, attuning or relating to others;
Sleep disturbances, trouble getting to sleep, sleeping badly, feeling tired and worn out as a result - which makes all of the above even worse;
... and that is just the tip of the iceberg.
