cutting and other means of self-harm tend to be taboo subjects, the people around you—and possibly even you—may harbor serious misconceptions about your motivations and state of mind. Don’t let these myths get in the way of getting help or helping someone you care about.
Stop saying yes to everything and everyone. Stop agreeing with people just so you don't upset them. You're not a pushover. You were not put on this Earth to be stressed and miserable so others can be relaxed and happy (at your expense). Start protecting your time and your happiness. If others can't handle it, show them the door. Kick them out of your life and don't look back.
