OCD due to hypersensitivity?

When I was younger, probably from like age 4 to 7 or 8, I had been extremely hypersensitive. I would refuse to wear clothing unless all the tags were cut off, would cry if my shoes were different tightnesses, and hated playing in the snow because I feared getting snow in my mittens or up my sleeve (I would cry if it happened). I'm 17 now and starting to think that my hypersensitivity has turned into OCD. I feel very overwhelmed by certain things, sometimes smells, sometimes the temperature of a room, but I find that it's mainly objects. I feel the need to make sure there isn't a single thing on the floor of my room/closet. Also, I can't fall asleep unless all my binders are in my backpack the night before I go to school (and the width of them is even on both sides of my backpack to balance the weight). Im bothered by, I don't want to say angle, but the position of certain objects in a room. Like on my desk at school, my paper/pencils/laptop etc must all be pointing/facing one way or I feel like my desk is crammed and I get overwhelmed. These may just be weird things that I feel necessary, but I also fear the worst in situations. For example, if I see someone kind of trip or stumble, my mind instantly flashes to what would have happened if they had fully fallen and hit their head. Are these signs of OCD or no?

hi H.. nobody here can diagnose you with anything. however, it sounds like it's causing you distress and i'm sorry for that. it's hard to pinpoint what exactly could be going on, i mean whether they're just quirks or OCD. do you think something bad will happen if there's somehting on the floor of your room for example? or do you experience intense anxiety when it happens? i think the best thing you can do now is see the doctor and get a proper treatment if you feel like it's beyond your control. and perhaps try to expose yourself. good luck
