I met an accident and have a grade-ii contusion of posterior horn of medical meniscus. I am following the diet & exercises. Due to pain I am not able to sleep well. I am feeling depressed a lot these days. I feel alone. I am getting angry very quickly. I am not able to concentrate well on anything. I am feeling a lot nervous, when people around my hands shake even while holding a glass of water which doesn't happen when at home. My age is 28 and I rarely used to drink, 10 times in my whole life. Even at office, I get lost in thoughts and my work rate is slow. I am loosing my confidence. How to get over this?
