I went to a huge university (FSU) and stayed for two weeks before I went back home. I was as miserable as you are. I completely understand where you're coming from. I even had friends at the school, tuition paid for, and a job lined up. But I couldn't do it. I had some sort of mental breakdown where I was going to attempt suicide if someone didn't come get me and bring me home, so after two weeks of texting my mom and telling her how much I hated it there, she came and got me and took me home. I felt like a huge disappointment too, and my aunt told me I was doing it for the attention (but that's another story). Don't feel bad if you have to come home. If you're like me, a large university just might not be your style. Have you considered community college to start? That's where I ended up, and I lived at home. Once I graduated from there, then I went to a university, but a small one, which was only 18 miles from home. I'd say to give the university a chance, but if you really are as miserable as I was, going home might be the best option. Check out your local community colleges. I waited a semester before I started at the community college and I just worked for a few months until school started.
