Grief and overthinking. Of what i want.

Suffering from depression and overthinking due to breakup feeling cheated since almost a year now. Keep over analysing situations and know everything i am supposed to do but have my CA Final exams in few days so i just cannot enjoy freely since this whole year n now wen m alone studying i am not able to concentrate. Also what i read online and ppl suggest is not possible bec i dont have friends. The ones i have idk i dnt feel connected any more. I behave like i have all the answers to my questions but i dont implement and accept the fact n keep thinking and thinking for hopes and get stressed up. I dont love myself the way i look. Not able to accept reality. Lack of confidence. I have read Law of attraction and got so obsessed with it and astrology n stuff to make it work which gave me more stress. Like i am doing things which i know arent practical and myb superstitions but idk m jus doing it out of hope and get tired of no results. Feel tired and cluess of what i want.
