BE HONEST IIN I feel like no one cares about friends these days?

I have a friend like they did so much for her spent hours on the phone listening to her cry about her anxiety.it ruined one of my relationships because me girlfriend at the time said she was too needed but as far as I was concerned if my friend needed me I wouldn't turn my back on them....the fool I was. Now she has a boyfriend to distract her and she's training to teach and all of a sudden doesn't have time for me. Cant remember who said it, it was a celebrity in a interview i watched years ago but they said you get two types of friends in life, friends that will energies you and you them. Then there are friends that are drains, as in they will just drain all the energy out of you, these are the selfish type that only talk about themselves and never ask what's going on in your life and drain you untill there is nothing left. Don't need that in your life.
