Hello LOVE! (I like the sound of that! assuming u'r a female!)
First of all, DO NOT withdraw nor start over and apply as a new student. Why put yourself through all of that painful process again? I'm sure with your good DAT and good undergrad GPA you can get accepted again to entering class 2005 which means u wont graduate until 2009, ouch! Time is money in dentistry! You've come a long way from filling out personal statements and asking for recommendations! just thinking about it making the hairs on the back of my head stand up! giving me goose bumps!
I think u have several options to consider:
1. Hang in there or ask for a leave of absent, take a yr off, start the 2nd yr in 2005. This is your back up plan. Maybe u'll change your mind or your circumstances change by then.
2. If u'r still thinking about transfer then schedule an appointment IN PERSON with the Director of admissions of the particular school that u'r interested in, discussing your situations. You'll find out exactly what are your chances of getting a transfer this yr or next yr to the new school, hopefully! whether you'll have to repeat 1st yr or take additional classes.
Transfering is not difficult when u have good academic standing (A's and B's, C's dont look good, Ds out of luck) and school support (u'll need the Dean's letter of approval/recommendation for transfering.) 4 of my classmates transferred after 1st yr for various reasons. I myself thought about transfering, filled out applications but didn't go through w/it after meeting new friends, frat parties, adjusted to home away from home....; plus the idea of starting over or taking more classes didn't sound too appealing to me.
Check w the schools that u want to transfer to for specific requirements. Many schools do not accept transfer students "under any circumstances". Most other schools do but have different requirements and process for transfering.
Good luck LOVE!
