Hi everyone. So I decided to withdraw from my program and return home. I got home today.
I felt a lot of things about making that decision -- shame, embarrassment, anxiety -- but honestly, I feel relieved.
I thought the homesickness would get better. I thought I would adjust to all the changes I was experiences. But it never did. While all the other exchange students were having the time of their lives, lamenting that we "only" had two more months left, I was dreading getting out of bed and counting out the days before I left.
I recalled something my therapist said to me back in November, when I confided in her that I was unsure if I should go or not. She said "If you aren't happy, you're not going to have a fun semester, no matter what people tell you about studying abroad. If you spend your semester miserable, it's not worth it."
I took those words into account, and with them in mind, I decided to go because if I didn't I would always regret not knowing what could have been, but if I did, I could always come home if something went wrong. Well, I was miserable, and my therapist was right, it wasn't worth staying when I was miserable.
My only problem now is that I have to find something to do for the two months between now and when my new job starts in June, but at least I can see my therapist again!

Thanks everyone for your support.
