I'm 20 years old, so i dont know if i'm within the gen Z range. I have a facebook and an instagram account. The problem is i think i don't know how this game works. I see some of my friends post mediocre photos or posts and get hundred of likes, others get a couple but they don't care. At first, my posts didn't get much traction and i was always shy to upload many photos. Nowadays, when i want to post something that i find interesting and talk about in the comments, i always think "what if no one cares?" "what if i don't get any likes". That has completely discouraged me for participating in the social media game and impacted my confidence. Now i only consume other peoples content. I see my friends talking about when to upload a photo so they can maximize their likes and i feel so out. It's like we have one more thing to compare one another. I'm not saying my friends value me for my likes, but i feel like it subconsciously creates a difference between us. Maybe i'm just very insecure or jealous but that social media thing just magnifies it.
