Sounds exactly like me 5 years ago - couldn't eat - scared of everything - scared of the sun going down, could not leave the house - total anxiety and paranoia. It started right after i had 3 mercury fillings removed from my mouth, got tingling electrical shocks in my neck, severe lethargy - then doc gave me 3 rounds of antibiotics - then the nightmare started - like awake in a nightmare - lasted for years - praying to God all the time to heal me - i finally found a book that explained everything - Medical Medium by Anthony William. I had Epstein Barr and Shingles viruses dormant in my organs but the heavy metals and antibiotics are a favored food of these viruses. Stage 4 of Epstein Barr is anxiety through the roof, dizziness, fatigue, tinnitus, fibromyalgia, muscle pain, joint pain, tingling, numbness, eye floaters, insomnia, esophageal spasms (throat closing), chest pain and tightness, asthma caused by EBV inflaming the vagus nerve. Heart palpitations, result from build up of EBV poisonous corpses inn the mitral valve. You can recover by taking a few steps. 1. Heavy metal detox smoothie (cilantro, wild blueberries, banana, spirulina, barley grass powder, dulse flakes) Just get what you can. 2. do not eat foods the feed viruses: eggs, dairy, mercury laden fish. 3. Eat super foods papaya, mango, sweet potato, wild blueberries, spinach, celery juice, parsley, cilantro, organic apples and pears, potatoes. 4. Eat very little meat - the liver is already clogged and battled the virus - and any type of meat fat bogs it down even more. Get the book and it will explain everything.
If you don't get help you'll never know, will you? Get help. Find out if something's physically wrong, then get into therapy. The longer you wait the worse it will get -- avoidance feeds on itself. I know this is easy to say, and I'm no better at doing it than anyone else, but if you stay where you are you will stay where you are.
