Let me make one thing clear:
There is NEVER a convenient time to say goodbye to your friends, pack up your belongings, and start all over at a new school. No matter what time of the year you decide to transfer, you are going to feel like an outsider when you arrive at your new destination. Having recently gone through the transfer process, I can personally attest to feeling lonely, scared, nervous, and mad at myself for leaving my comfortable life at my previous university to begin again at a new school where everything seemed so foreign.
Recognizing that the college I envisioned myself graduating from is not actually the best fit for me was a hard realization to come to.
