is this severe loneliness or first stage depression?

Have you ever experienced it that you can't or you don't want to go to sleep yet because you are so lonely and sad and you are waiting for something that would make you happy before going to sleep. Like maybe, an email that brings good news, or a message notification from the person you like a lot or a funny comment from a friend on your facebook or get several likes on your recent instagram photo. It happened to me often. I can't sleep because I kept on waiting for something that would make me happy - not the usual everyday small things that I just take for granted now - but i am constantly waiting for a surprise that would make me happy.
@Kathy Miller: I appreciate your offer. So kind of you. Thank you.

@ALL HAIL JESUS!:
I am a believer. But this time, I think I need a human understanding. I need to feel a human's hug, exchange views and opinions with a human. I'm sorry, I can't just live with Jesus in my heart alone. I also need people. And because I am working online, I only am interacting with friends through the net. I need interactions with people which seldom happens now - two years - because I am working online 16 to 18hours, 6days a week.

Really, it's great to interact with people just like this one. Not much interaction here but seeing all your answers made me realize things and I think I know now what to do and what's been lacking. Thank you all! I appreciate all your answers.
