Is there actually something wrong?

So im 17 years old, and all my life I have been dealing with something that im not sure really exists. Ive always been like this, and its never been different. When somethings changes in my life whether it be as significant as moving houses or as insignificant as me having to buy a new binder thats not the same color as my others, I get highly stressed out. Its no OCD well at least i dont think it is. Cause thinks rnt perfect or neat in my life watsoever. Except my schedule. Every Monday is the same. Every Tuesday and so on. If something gets off, I become extremely stressed and began crying. My laptop broke the other day, which was my life cause it was something I could always get on that was going to be the same everytime. Well my mom allowed me to have hers, and when i got on and saw that everything was different, I got so stressed and began crying, until the laptop was the exact same as before. It takes about 3 weeks to get used to something. I wont buy new phones, or new clothes and if I do have to buy bigger clothes, I buy the same thing just a bigger size. I wear the same pair of pants everyday, but I wash them everynight. Another thing is, I dont like social interaction, its not like I hide form it im very outgoing and fun loving person. But when it comes to talking to people, I dont like it. Cause everything is constantly changing when your having conversations with people, and I cant really handle it. I just wanna know if there is an actual word for this?
