<human>: Condense the text into a few key points

Ok, so I'm a 19 year old guy. In September of last year I started college. it was a course that wasn't exactly my first choice, but the best of a bad bunch. In January of this year, i just decided it wasn't for me. i thought it would grow on me, but it never really did. But I stuck it out until May cause I wasn't gonna be getting my registration fee back and i had nothing else to do.

So all Summer, the plan has been to enter in to a new course, the one that I had first intended on before my slightly lacking results. It was a sort of 'back-door' style entrance into this course. But now, I'm not even sure if i want to do that one! I'm starting to think that it just sounded so appealing when I was in the course I hated. 

I have an interview tomorrow for the new course. I'm gonna go, but I'm unprepared, frightened a little and honestly, I'm probably gonna mess it up. 

I've thought of so many other things to do instead of this course. I've been thinking of getting a job, taking night-time classes in something like cooking, even joining the army came into my head! I'm so fucking confused! The worst part is, I haven't said a word to anyone about all this. My family obviously knows about the whole switching courses thing, but not about how I'm feeling right now. And I haven't told any of my friends about any of it! I'm useless at opening up to people about how I feel. My mom normally knows when something is up because I go all quiet and a bit moody.

I need some help, advice, input, anything! Please guys!
<bot>: I'm confused about where my life is going in terms of my education. Too nervous to talk to my family. Friends haven't an idea of what's going on with me. Need advice!
