4. They cancel plans

Has your loved one been canceling on you a lot lately? Have they been showing up uncharacteristically late or started skipping school/missing work? Try to talk to them about it and ask them why. Even if their reasons seem plausible and they reassure you that everything’s fine, keep a close eye on them still. Then, if they start bailing on things that are important to them (like that recital they’ve been rehearsing for months, or that competition they worked so hard to get in), then that’s a red flag you shouldn’t ignore.
