ocd is exhausting

worrying about things gets so mentally and physically tiring. i can sleep 14 hours and i still feel so incredibly tired. every 5 seconds and 24/7 i’m always thinking of things that can make me sick. friends and boyfriend drinking out of my water bottle, instantly my brain goes to if they have a disease neither of us know about and they’re passing it on to me. or what bacteria or germs are on their hands that will get on mine when i grab the water bottle. then about what happens if i run out of hand sanitizer or can’t get to a sink. today i went to the mall and just everyone around me really stressed me out. people coughing, rubbing their noses, walking in close proximity. i just can’t deal with it. i want to close myself off and stay in my room 24/7 but i know that’s not healthy for me. i’m also in college but now on break and i also worry about having to go back to showering in the same place as people i don’t know. what if they’re washing stuff off of them and it could get on me if i accidentally touch it? ik this thought pattern is extremely detrimental but i just can’t stop it from happening. one of the big things that has been bothering me is concerning my dog. i love my sweet baby so so so much but my brain automatically goes to him having a disease or rabies that will pass on to me and i’ll die. i get weird when he licks me because i don’t want him to think i don’t love him because i absolutely adore him but it just freaks me out to think of everything that could be in his mouth on my skin. i can look at my thinking and know this is not logical thinking but i can’t stop it from happening. ocd keeps me from loving my sweet baby boy. i guess the whole point of this post is to ask if anyone knows how to stop these thoughts from happening or not letting my mind dwell on them. when i feel this way i try to talk to my boyfriend, who isn’t always available because he has a full time job and can’t be on the phone all of the time. he is the only one that comforts me and makes me feel okay. i also get those really intrusive thoughts when he and i are kissing or having sex, like “what if he has meningitis and is spreading it to me” or “he’s giving me an incurable std that will kill me” when i know he is loyal and has none of those things. he’s also noticed that i’ve been very anxious and obsessed with these things. so i’m reaching out to anyone who knows any type of coping skills as a last resort. please, i feel like i’m going crazy. if you have anything, please let me know. also, thank you for reading until the end of this, i really appreciate it. ik it’s long but i felt like i needed to vent :(
