Omg I have the most severe case of ocd but during some periods it's stronger than others. The worst one I ever had was an obsession that everything I touched would make me dirty, I couldnt touch anything. For example when I would go out come home I literally had to empty everything in my purse and disinfect it one by one and I mean everything in it and I'd have many things in my bag. I would take out every card in my bag and disinfect with alcohol and put them back in after disinfecting everything inside Id disinfect the bag itself, the outside of it, the handles , everything and it would take me about 45 min sometimes longer but the worst part is that due to the constant alcohol use my hands became so dry eventually leading to cuts, open wounds and the craziest part is tha the ocd was so bad I'd actually have to keep doing it putting alcohol on the opened wounds. I'd scream cause it burned so bad but I couldn't stop. My hands looked horrible, I'd be so embarrassed when people would look at them, I'm sure they thought it was some kind of disease. It drove me insane. Now I still have ocd but in a different way just like touching something and have to do it again for 10 times.
But yeah ocd is the worst. People don't know to what extent it cripples your life.
