Hello and welcome!
Can you maybe share a little bit more detail about what you're going through? Your thought processes and any compulsions you are having? How is this OCD like behavior centered around a certain person? Is this a love interest? Former or current?
Do you have any history of OCD or anxiety and if so, have you tried any treatment?
With some more info, we'll be able to offer some more specific advice.
Yes....OCD can present in a variety of ways.
