Saying “no” is not selfish. In fact, if you drain yourself completely, there will be nothing left to give. Remember that self-care and preventing burnout is healthy and will help you continue to be a loving, caring person to the people in your life. So, next time a friend asks you to do something you’re not actually interested in, be honest about how you feel, and say that you would prefer to just stay in and rest. If they get offended by this, it’s a sign that they may be selfish or insecure. True friends will want you to take care of yourself before you’re ready to socialize again.
