CarpeDiem, I think it's normal to feel that way even if you're doing just fine, so even if that feeling is uncomfortable at first, know that a lot of it will probably subside over time. Most people will always feel "behind" throughout vet school, so it gets easier once you accept that will be the case. It's virtually impossible to do all the readings ahead of time and review lecture notes from the day before, while studying for imminent exams. At first it can be really hard to know what information is really pertinent, so the volume of info can seem impossibly overwhelming. The best advice I've heard is to keep studying the way you are now until your first set of exams and assess from there. Chances are, you'll realize that half of what you're doing daily does not need to be done as thoroughly as you're doing it now.
Like in anatomy when my lab partners are zooming ahead and naming off every single muscle, origin, and insertion and I still don't know half of it. Then I ask how long they study and it seems like not nearly as much as I have been doing. Also I want to come to anatomy lab everyday on the days after anatomy but the group did not really seem like they wanted too. So I end up going in there by myself and trying to figure out things but I don't even know if the muscles I am looking at are even the right names I am studying.
ok, that's a really unhealthy mindset, and that has GOT TO STOP. Feeling inferior will only hinder your learning. It's hard to get stuff in your head when you're feeling intimidated (been there done that, and never again). Maybe your lab partners are lying, and maybe they're not about how much they study. Or, more commonly, a lot of first years tend to focus most of their studies on anatomy (kind of like how UGs taking orgo tends to focus all their energy on that). If your group is amenable, then say "hey, I feel a little behind, could you guys help me out?" And maybe let the other people do the dissection, while you spend lab time learning the muscles (origins/insertions can be learned later). If it helps, start at one edge of the part of the body you're doing and start identifying them in order. Ask if you get stuck. If your group isn't very nice, flag down a TA/professor or ask for help outside of class.
And don't rely on your group to study anatomy outside of lab time. You can go in yourself, with another friend, or schedule a time for extra help with a tutor/professor if you're really struggling. I went in almost at least once a week with my friends (not lab partners) to study and compare specimen, and that's when I did a bulk of my learning. I'm not sure what resources you're using, but if you're really shy about going into lab by yourself, you can try studying first on virtual canine anatomy or a coloring atlas.
Definitely compartmentalize your learning because if you go in with the mindset that you need to sit down and emerge 10 hrs later knowing everything, it will be overwhelming (I mean hotdamn, it'll be like "ok muscle 1 is located . . . its origins/insertions are ____, it is innervated by X, supplied by Y, drained by Z, it does this action when flexed if the limb is weight bearing, and that if not. holy crap! there's 50 more of these and it's already 2 am....") Do bones one day. Just work on identifying mm another day (or two). Then read the text if you want to about the finer details about function and whatnot with respect to origins/insertions. Don't worry about vessels and nerves until once you know the locations of the bones and mm, because it'll blow your mind trying to identify them since their locations are described with respect to bones/mm (and it's easier to learn what they supply/innervate if you already know the mm cold).
The stress is really getting to me. I feel lost not only in class but in this new town. I miss having my dog here but I don't know if I will have time for her since I am at school from 7-8am to 7ish at night so I left her with my parents. Does not help either that my long term relationship just ended basically because it turned long distance.
Week 2 starts tomorrow and thus starts the quizzing. I can't even sleep. Hence the 1am post.
The start of vet school can be a really tough transition (academically/life-wise), and it feels infinitely worse when others around you seem to be having a ball, but chin up! it'll definitely get better.
