How do I know if a friend is toxic?

Warning signs include constant put-downs, jealousy of your success, gossip about you, one-sided effort and pressure to do things you dislike. Everyone has bad days, so look at the pattern. You can talk to them honestly or step back.

Ask yourself after you meet them: do I feel lighter or drained? Notice if they put you down, compete with you or only call when they need something. Try one honest conversation about what bothers you. If nothing changes, spend less time with them and keep the door polite.
