Good friends are supposed to support you when you need them and speak highly of you when you’re not there, so if they do the opposite, it can be a red flag.
A sense of belonging is important when you’re with friends, so it’s not a good sign if your friends start leaving you out and excluding you from plans.
Friends should be making your life better, not harder. If they drain your energy, make you feel sad, or make you feel bad about yourself, then they’re probably not worth it.
Arguments between friends can happen, and that’s okay, but if you realize that you feel negative most of the time, it might be time to find some new friends.
