You don't have to keep being the person who says yes just to avoid disappointing everyone. You don't have to stay available all the time so people won't call you selfish. The truth is, you've spent so much of your life putting everyone else first, worrying about whether they'll think you're cold if you take a step back. But you're not cold. You're tired. You're allowed to be tired. You're allowed to say, "I care about you, but I need space," without feeling like you've failed anyone. You can still be a kind person and decide you've given all you can for now.
