There's a term (and yes, this is a real thing) called a person who is 'toxic to you'. After being with a toxic person, you might feel drained of energy, frustrated, upset. They might be a nice person, but they can seriously injure your life.

Is there anyone you can think of who's toxic to you?

If you only add to someone's life, you don't gain anything through a friendship with them...just remember that your own happiness comes first. Always.
