Hello , I see the thoughts are taboo which are harmfull to you , if u had OCD before the contamination can occur even after years soo ,I suggest you to go for a lab test if possible , but I want to make it clear that if you are repeatedly surrounded by a particular environment ,and thinking same past forbidden thoughts can destroy you internally dear, so please keep in mind that no negativity is powerful then you . you can really live happily by thinking goodness for yourself ,do your hobbies ,listen to music , and meditate . ☺hope you feel help full.
