Why am I, double minded, confuse, unable to focus and with lack of energy?

Dear ma'am, I am going through a tough mental state right now. I do not know what state is this. It may be fear, lack of confidence or anything else. On 25th November 2019 I underwent surgery for anal fissure and piles. It took a long time to heal as I was suffering from constipation even after surgery. Every morning i would have a trauma like situation before going to bathroom. My stool would be hard enough to pass with blood both before and after surgery. I generally get nervous after seeing blood. In the meantime surgery has been healed. Even today I have constipation. I suffered from rhinitis like situation after surgery by consuming fruits and curd to make stool soft. feel difficulty in breathing With these medical conditions I developed a mental condition at which i always feel sick myself. No mood or energy to do anything. Fearing for life. When I wake up in midnight it gets very tough again to sleep. I sweat a lot. There is so much negative thought in my mind at night. I feel heavy in my head. I fear every sound I hear which disturbs and terrifies me. I consulted a psychiatrist 7 days ago; he told me that it is fear and lack of confidence. He has given me medicines to overcome fear. Kindly suggest ma'am at which state I am and help me. I am actually obsessed with my health and my life. Every moment I feel I would die. Nervousness grips me. I have lost weight of around 18 kg post surgery.
