Suggest Treatment For Anxiety And Depression

Hello, I m 22, I feel like my life isn t where I want it to be. I m in college, but I feel stupid going. I fail most of the classes or I have to drop them because they consist of presentations. I can t even hold a simple conversation with my own mother. Ive isolated myself form everyone including my family. Im always in my room. Most of the time i feel like i don t belong in this world and i want to take my own life away. sometimes i also get urges to kill people. the thing with that is that i hate the site of blood. i don t know who i am. i feel like a failure i want to work for law enforcement , but im too fat to even do that. and im not smart enough to do anything else. i don t know what to do. i already over dosed and i had to go the hospital but i didn t tell them i over dosed and they just thought it was my body reacting to the medication. I feel so lost.
