So every Sunday my dad and stepmom go to church. I don't believe in it but the people there are great people so I go. I've been going for a couple years and there is a group of people who always bring food, 2 girls who are juniors are some of the people this story contains. Before I went today my dad showed me a text where they said had a free pass to six flags and asked if I would like to go with them. Right when I read it my mind thought no, I started thinking about how awkward I would be and I wouldn't know what to say and how to act. Keep in mind I'm a 15 year old guy, and I don't know why I was thinking like this. If a group of my friends from school invited me I'd say yes in a heartbeat and leave but this was different. I've had an instance like this before where I dated a girl back in 2015 and I was insanely awkward and we never did anything or went out anywhere and it just felt weird. I went to her birthday party and she wasn't there so I sat and when she walked in we started texting, yes TEXTING right fucking next to eachother. I dont know know what I'm afraid of, if one of my friends was going to the six flags thing I'd say yes not sure why that'd make a difference but still. When I was 12 or 13 I was dating someone and I wasn't awkward at all I didn't give a shit, I guess because I was younger or something but I never cared what the person thought about my appearance or whatever. The point is, I missed out on an experience that could be good for me, like get out of the fucking house for once. Now, I'm not a kid who sits in his room all day I play soccer on the occasion and go outside but it's mainly just me alone practicing. Is my low confidence due to the fact that I don't socialize with anyone? What do you think? I don't know how to improve.
