people who can afford to leave social media aren't prolly in circles that have heavy uses of sm. I would love to get off sm, but literally can't afford to, because it's almost essential to stay in contact with friends and know about events.
You have the choice. If you've weighted your options and decided to stay on social media because you value what it gives you more than what it takes, that's your choice. But you do have a choice.
Also, if your friends disown you because you choose not to use social media, are they really your friends? If they don't respect your decision, are unwilling to speak with you except through social media, then I personally wouldn't consider them friends. But that's up to you. And you can always make new friends.
i only have the illusion of choice, because the real choice is between being socially active and being a social outcast. the world has moved to social media. its sad, and I wish I could do something about it. friend group is making plans? on Instagram. wanna be in the know of what's going on? on twitter. want to be updated about your assignments? your class is officially only on WhatsApp. wanna apply for a job? keep in touch with professional colleagues? only on LinkedIn and whatsapp. this is what my world as a young adult in a developing country is like. this is what has happened because not a lot of people had access to pre social media internet. and the first device a lot of people used is a phone. more so for younger people.
