Stop saying things you don't fully feel.
Don't say " I love you " unless you're sure that it's real. It's not a temporary feeling. you're not alone and bored.
Don't say " Okay " when you want to say " I can't " because one day you'll say it and they'll think you changed.
Don't say " I'll always be there " unless you mean it. Unless you make sure you can stay as long as you're alive.
Don't say " I promise " until you are capable of doing that thing you promised. Some people build scenarios, maybe lives on this promise.
Don't say anything until you feel it. Deep inside.
Like you're sure of it as much as you're sure that you're breathing now.
