Welcome @annirose! Wow you're 16 yrs old and so articulate. I used to teach high school English for years in Canada, and most people your age weren't so connected with the idea of community as you seem to be. I'm glad that @Nuckly introduced you to all of this.
I belong to several groups here who welcome, support, and mentor new people like yourself. They each have a Discord channel as well, which if you don't know, is another place that we connect, chat, share ideas, contest, problems...whatever you need actually. The groups are @newbieresteemday, @greetersguild, @asapers and @helpie. We overalap a bit, but that's a good thing because you can get to know so many like-minded people who are really interested in selfless, community spirit. We purposefully go looking for new people because truthfully, it can all get a little overwhelming ;)
If you have any questions, feel free to ask. I'm also going to come back here as @newbieresteemday and resteem your account :)
Again...welcome to steemit!
