I'd read news of how Facebook keeps people addicted or how they try out psychological experiments on its users which left me uneasy. Finally, when the Cambridge Analytica scandal broke and revealed that Facebook sells access to your personal messages, thst was the final straw. The biggest problem with deleting your account is that your contacts assume that you just deleted them and think that you're mad at them or something. It can have a real world impact. But I've been way happier texting friends and family and talking with them directly. It's been so much healthier than leaving "likes" on wall posts. I'm never returning to social media.
