schedule ocd?

hello! i am currently a student, and at my school i have the same classes every day in a very specific order, so my brain has gotten used to going the same way. this isn’t a problem when that method is actually the fastest way to get to my next class, but now i have a compulsion going from one specific class to the next to go the long way around and then make sure i can see my friends through the window of a class pass by. this takes up wayyy to much time in my schedule and ive even ended conversations awkwardly so i can go out of my way to do it. my brain is telling me that if i skip for even one day this weird pattern that something horrible will go wrong in my life, and due to something sad that happened in my life recently that i’m sure was just a coincidence of me not going that way that day. my brain is convinced that my habit is backed up by some strange cause and effect. i was just wondering if this really is ocd or just something strange that i do. if anyone has any tips to start breaking this or if you want to share your own story or just chat, please feel free to comment or reach out! thank you for reading!
