I am so sorry that you are feeling like this. Do you think you could go to see a doctor there and get some medication that will help you focus so you won´t need to drift towards being an F student? I know my depression is also making it very difficult for me to focus and makes everything much more difficult to cope with. There is help to be had, but you must look for it. It is good that you post here because it is good to vent and not bottle things up. Keep posting here!
