((((hugs)))) to you!!
Starting off with such large classes can be intense and overwhelming. I know that I wouldn't like it!

Payne1 had some very helpful advice for you. Give it a try!
I was older when I began my college education & very accustomed to being alone and doing my best. So, I'd adjusted to that YEARS before!! I also went to a community college for the general education classes, where the classes are both smaller and cheaper. When the last 2 years hit, I then moved onto a state college and classes weren't any different than they were at community college. So, that worked out pretty well for me.
I know that these past two weeks have been very hard for you. I can truly understand that anxiety and depression. But, try to stick it out. You will find others that are similar to you soon ~ and once that occurs, things will become a whole lot easier! Try to be patient.
