I had it too since I was a child. I had to experience a lot in my life and learn from it. I had to end toxic relationships many times...
Over time, I learned to set limits. When new people appear in my life, I try not to get involved emotionally, but only to show them the way. It is emotional involvement that drains energy. A small group of close friends also helps. And knowing that I can't change anyone. I can only help those who want to change.
