Home school to private school?

[Elvalight]

I've been homeschooled pretty much my whole life, and it all went well for a while. I was getting out and socializing with kids my age often, understanding what I was being taught and everything was going smooth.
But then, after two of my sisters grew up and left, leaving me with only one other sibling( who is almost done with high school), it of course got more lonely. We live pretty far from anything where I'd be around kids my age these days, and seeing how it is much harder to make friends when you're a teen, I haven't been able to make any friends. My mom deals with lyme disease, so sometimes she wakes up feeling tired, plus she is a lot older these days, so I don't always get enough time being taught by her. She tries, and I do appreciate it, but I tend to need to have things explained to me in detail, and she usually just gives me books to read quietly. We both kind of acknowledge the fact that we don't really get along too well by nature. We often get into fights without meaning to. She said one of my options was to, next year, attend a private school. This may not seem like much, but it's scary for me. I've never been to a place like that. I get that I'm falling behind in school, not because she is a bad teacher, but because it just doesn't seem to work for me. I need people who actually check the work I do for errors and will give me a proper grade, not based on my mom feeling sympathetic. I want to form actual friendships with kids my age and not be alone so often. I hope these seem like valid reasons.
Sorry for that huge story, I just want to know what to expect. I'll be going into 10th grade, most likely into a Christian school, and I have no idea how to act or what it's like.
Any advice you could give would be great, thank you.

In December of this year I switched from online public school (previously homeschooled) to public school, so I imagine it was a pretty similar transition to what you may experience. For me, it was fairly easy. Just go with what happens and laugh off anything that might come up. The days will feel a lot longer and like you're doing a lot more, but the work isn't difficult. It's going to be pretty tough finding friends, especially if you keep to yourself, because nobody will go up to you and talk to you. You need to open up and smile and talk to others. If you do that, you'll have friends in no time. As long as you keep up with your work and do what you're supposed to you'll be fine. Also, if possible, avoid the cafeteria if you have nobody to sit with. I've sat on the floor multiple times before and it's extremely depressing. Avoid that.

I understand your reasoning for wanting to go to a real-life school :) I was homeschooled a few years ago and I didn't really enjoy it that much.

Private schools are no different to public schools especially when it comes to socialising and having fun. You can introduce yourself to people and go to school clubs. School clubs are really really good because you get to meet people who have the same interests as you! As Luminous said, the days will seem longer as you will most likely be at school for longer hours than you're used to. There will be the occasional snobby kids, but just ignore them. I hope everything goes well :)
