You mentioned cholesterol....if you are obese or overweight, that might be something you want to take into consideration. From the way you describe things, its best to go see a doctor and a counsellor to try to understand the cause of anxiety. Pills can take care of the anxiety when it sets in but you'd want to address the cause in order to cure it. The counsellor can help identify the problem. You can also try yoga and breathing exercises. Hope this helps. Take care.
