Hi. I'm new to this forum, and I suffer from intrusive thoughts. I have not yet been diagnosed with any disorders. Sometimes I doubt that my thoughts are intrusive. How do you tell the difference between intrusive thoughts and real thoughts? Is it possible to suffer from intrusive thoughts without any disorders? Sometimes I feel like I actually want to act out these thoughts. Are intrusive thoughts reasonless or do we have a reason for why we want to act out these thoughts? What causes these thoughts?
