According to TIME, Instagram is the worst social media for our mental health. (Source) It is associated with high levels of anxiety, depression, bullying, and FOMO, or the “fear of missing out.”
I think this can easily be avoided by just not following people who make you feel inadequate or unhappy. (That may not solve the FOMO, though.) Most of the accounts I follow on Instagram are cats and golden retrievers, and I’m doing great! Although I have a diagnosed anxiety disorder, I do my best to make sure things like this don’t trigger it.
