Hello! Greetings. From what u have told I am able to understand that u also suffer from the most common part of any Individual called stress. Of course every person's stress perception is different from another and has to be addressed individually with special care. U also seem to have developed symptoms of depression, namely helplessness and worthlessness and negative cognition.

Hii there Everyone faces such difficulties in life u are not alone. U need to be dedicated towards your work. Dont get down by failures. U need to stick to that task, learn from others and if they have achieved u can too. Start from small initiative, Take pleasure in small achievements this will boost up your moral and confidence.
