Am i dangerously attention addict?

I don’t want to specify my gender. As long as i can remember, i have felt a need for attention and for talking with people. When i am alone, i feel sad and i want to talk to people who show interest in me and have conversations with me.

Sometimes, when i feel like nobody wants to talk to me, i end up posting sad things on social media so that people will show interest or message me.

What could this be caused by? Am i addicted to attention, or could it be something else?
