Ocd

I feel like my whole life I’ve been overthinking everything. I remember having really bad intrusive thoughts as a kid but I thought I had gotten over it. I feel like I’m starting to see that it’s just not manifested in different ways. I tried to bring it up with my therapist but she thinks it’s just anxiety. I feel like it’s something more. Does anyone have any advice on what personally showed you what was the difference

I struggle to understand when a thought is an intuition or intrusive, especially with relationship OCD. My problem is I have a great intuition. There have been many times when I thought something that made me anxious, and said to myself “it’s only OCD”, but then that thought turned out to be true. But there have also been times when it turned out it was just OCD.

Please how can an intrusive thought be distinguished from our own thoughts ?
