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.
