Transfer student wanting to transfer back

I’m really conflicted because I transferred from one college to the current college I am at right now. I am a freshman in my 2nd semester. At my first college some things bothered me towards the middle of the semester but towards the end things got better and I was sad to leave but I had already gone through the whole process of transferring so it was too late to change my mind. Now I find myself extremely unhappy at my current school and I want to transfer back. Now that I’m gone I realize the major problem with my old school was with my roommate and not with the school as a whole so I feel that it was stupid to leave altogether. Is it possible to go back and if so how soon could I go back? I am only a week into the semester here. Should I email my old school and see if they will let me come back.

Why not? Nothing ventured, nothing gained.

I would give them a call.
