I need something like social interaction or a distraction. Please help.?

This feels unusual and hard to explain. I'm nearing 19, I graduated early a few months ago, I'll probably have my driver's license within two months. In my current situation, my closest friend is moving away soon and I have no other friends in my area, my Mom gets chronic migraines and the medication for it keeps her in bed 90% of the time (or so it seems), and I was foolish enough to break up with my girlfriend six months ago due to my anxiety with school and thinking I couldn't handle a relationship.

All that aside, I fear I'm losing my mind or going through some form of denial. It's like I have no one close anymore or even people to talk to. I figure once I get my license I can apply for a job and meet people then, make friends and find something out. Till then though I have little I am able to do or know how or what to do.

Is there some place on the internet where I can find people to have one on one conversations with, something to make me feel less lonely. And I mean something like meaningful conversations, or stimulation conversations. Not anything like Omegle or Chatroullet, too often to I get greeted by overly creepish sexual comments or extreme (and pointless) swearing.

What can I do that can make me feel sane or comfortable enough to last long enough till I have the ability to go out and meet people and actually do things? I'd appreciate anything that might help fill this empty sickening feeling for now.
