Heh. I'm actually in the exact same situation. I've been homeschooling since the middle of 9th grade and I'm really over it. I have friends, but they're kind of fragmented and I only see them occasionally. I've been taking CC classes but it's not the same

It's not like actually going to a school, it's like taking classes and leaving, in my experience anyway. Although it's quite a refreshing change from being at home.
I'm planning on going back for the spring semester for prom and everything, but most of my requirements will be done so I can just take the AP classes I want. I'll just get the fun bits of the HS experience without having to worry about colleges or anything, and then I'm planning on going to a really fun college and making up for my study-intensive lackluster HS experience ^_^ I'm a really social person so I've been dying inside lately :S
What kind of homeschool do you do? Is it like a you make up your own curriculum kind of thing? Mine's actually sponsored by my school district so there shouldn't be an issue with credits. But you know, you might not need to actually graduate. A lot of colleges don't care if you have the piece of paper as long as you have the coursework and everything.
And yeah, I really wish I hadn't left in the first place

But at least we still have college, right?? And we can still make the most of our senior year
