What do I do now?

I used to be so talkative when I was younger. I always found myself in a group of friends and actually had a lot of people who liked me. I was never bullied or anything either, but ever since my sophomore year of highscho I've only had one friend: my older sister.

I went to the same middle school for three years, so when highschool rolled around I knew a lot of people and still had majority of the same friends. But as my freshman year continued on, I just felt tired. I suddenly hates talking to my friends and others at school. They just started to make me feel, like, drained. Like talking to them and interacting with them was sucking out a the energy from me.

By the end of freshman year I had one major friend, and then I moved schools. I had Facebook back then, so all my friends were friends on it, but I had the sudden urge to just delete them all. So I did. I completely wiped my Facebook page, breaking off of contact with not only friends but family as well. It made me feel guilty.

I only made one friend in my new school, and that was only because the guy liked me as more than a friend (I couldn't date him. I had just gotten out of a scary relationship). And ever since then, I've had no friends.

People just suck out all the energy I have left. I don't have online friends, and I don't talk to people at work so I dont make new friends. I'm just not sure what to do now. I'm lonely, and I want friends and a relationship, but at the same time I just can't deal with it.

Thank you for reading my long thread.
