im also in my first year and im sort of similar to you. Dropping out is something i think about fairly often, before i even came to uni i wasnt sure the course im doing is for me - im still not 100%. I from the strart went with the mindset, we'll see at christmas. Over the xmas holdays i am really going to sit and sort of evaluate the whole experince, getting away from uni i think will help. So i think i will stay on at uni but i'm still going to really think it through at christmas, and from the start i told myself i had to get to christmas and then see, loads of people also say uni changes so much in 2nd term .
Might be worth you trying that?
