Regretting Transferring

This past fall I started at a school far from home that I was excited about, I made some great friends, and had some fun, but was very depressed.I wasn’t homeisck, but something was making me miserable and my parents and I all thought the only way to cure this misery I was feeling at my school was to start over. So I transferred that spring, to another school, also far away because I had no problem with distance, and things were/are going well. But I regret transferring and think about my old school everyday. The climate at my old school was beautiful, and I do not like the cold. And I had such special friends at my old school that I can’t see myself replicating those friendships at my new school. I have thought about going back to my old school but am afraid my depression will come back. However, I look back on my time there and think, how could I have been depressed things were pretty good. Any guidance would be appreciated! Is it even a normal thing to transfer back to your old school?
