Commentitis 

The obsessive nature of checking your status postings on Facebook for comments every time a computer/smartphone is near. Lack of comments usually leads to more status updates, "Status Frenzy".

Commentosis 

Commentosis, sometimes known as Tweetpression is the depression that engulfs a person when the object of your affection online comments to the comment after yours, and in doing so neglects to acknowledge your contribution to the thread.

The object of your affection- "I really need to get out of the house tonight!"
A person you hate now- "Yeah, same. I'm gonna go train at the gym."
You- "It's my night off, can I shout you dinner and a movie?"
The object of your affection- "Have a great session at the gym!!!"
Your inner monologue- "Total commentosis."
