I'm sorry to hear about your troubles, AlwaysHope. If I can give you one word of advice it is to be PROACTIVE. Don't leave your health in the hands of someone else...such as your doctor. Can you see a good naturopath; preferably one who has his or her doctorate of naturopathy who can help you get your health back on track.
Write down your history in point form and take any medicine and supplements to show him or her. And most important of all, take questions to ask. Never mind the cost. This is your health at stake. The naturopath will create a healthy diet for you, probably encourage you to take probiotics (50 billion Garden of Life) to boost your immune system and to get plenty of sleep and exercise.
Our plates should be very colourful. You don't want to be looking at a plate of beige food. I think your naturopath can work with your doctor to get you off any meds that are giving you problems. There are more natural ways to cope with anxiety such as exercise and some natural supplements. Avoiding coffee and tea is a start. Aiming for at least 7 servings of fruit and vegetables is also a good start. I wish you all the best.
