Mental breakdown

I feel like I’m on the verge of a mental break down. I’m going to start off by saying I am a people pleaser and always have been. But I just can’t do it anymore. I have my parents pulling me one way and my significant other pulling me another. I honestly wish sometimes I could run away to another state and start fresh by myself. But I would never do that. How can I make others happy when I’m not even happy myself..?
