Social Anxiety 2

I sat in my house, playing on my Wii U. I've been doing the same thing everyday since summer vacation started when my mother was at work. Today was her day off so I wasn't alone. Later that day, I heard a knock at the door. I opended it to see her.
"Hey Tiara." My "friend" greeted. I saw her cousin was with her too.
"Hi." I said shyly.
"You wanna come outside?" She asked.
"No" I thought.
"I can't. I've been feeling sick all week and I'm helping my mother with something." I said.
"Oh ok." She replied.
"Bye!" Her cousin said and they left. I didn't lie about being sick, but I was about helping my mother. I just don't wanna be around her. Or anyone.

The next day, I was watching tv at my house. I grabbed my phone when I heard it ring. I saw I had a message from my "friend."
"Hey." She said.
"Hi." I replied.
"Are you home?" She said a few minutes later.
"No." I lied.
"Ok." She said. I sighed and continued to watch the show.

Later I decided to talk to my online friends. I think their my real friends then the ones in real life. Some of them were talking about the things they were working on. Others were talking about stuff that's happend recently. One of them talked about their boyfriend.
"What's the point in dating anyways?" I thought. Sometimes I wish I was like them. Outgoing and having real friends. But I'm not. I won't be like them because of my social anxiety and no one will understand unless they have it.
