Sorry to hear that: You may have some sort of anxiety disorder that's developed as a result such as post traumatic stress or stress reaction or even anxiety or depression. An assessment by your doctor will help you here as once a diagnosis has made there are usually treatments - psychological therapy, medications or a combination of both to assist you. All the best and hoping things turn for the better for you.
