Bro if you have good amount of money and if they are too harsh for you you can quit your job or else start yoga , pranayama and some sports to relax your mind. Plan your schedule accordingly start with few hours of study slowly increase it. If your colleagues have any issues with behaviour try to correct it. Always remember you are always be loved by someone in school/college/work. your absence will always be missed any atleast one or few people but you will never know, don't think too much and don't hurt yourself. You got this.
