I've created a social media account on Facebook about 3 - 5 times after continuously deleting my account. Right now, my account is deactivated. I kept coming back due to loneliness, I think, but I also realized it seemed to affect my mental health with me comparing my life to others and realizing how few people I've befriended in my life. It was pretty useless to have a social media account on Facebook when I didn't have many people to stay in contact with anyway.

As for when I first had a Facebook account, I'm going to assume around a year or three after it was created. I just followed in my immediate family's footsteps to create one. I later on found Reddit and I've been a member of Reddit for a while now, though I no longer post or comment, just browse.
