What to do when urges come back strong?😭😭

How?

And what is happening...let's say I come across a video of that person and then I stop the part where it triggers me and I deliberately imagine images of a sexual type, and if I don't feel anything, I look again, as if I want it or I have the urge to imagine it, i.e. I feel the need, and if I feel something or get a feeling in my groin and I feel like I fall into despair?

So my therapist told me to start telling myself every time I have an intrusive thought just say oh there’s that thought again, and don’t try to figure it out or do mental compulsions. Well our usual tactic of “there’s that thought/feeling again” is not working at all this morning. This morning I was having really bad anxiety, it hits hardest in the morning when I am lying in bed with my son and I know the thoughts could come at any minute. Well they did, and I immediately was like no please just think of anything else. Well in pushing away the thoughts, I had this really weird feeling like I couldn’t decipher between reality and images. I was just getting flashes of images that felt so real. Even though I could physically feel my body and know I wasnt engaging in the thought or acting on it. It was like a flash of anxiety that hit and I couldn’t tell what was real and wasn’t. So of course my mind starts trying to figure that feeling out and if what I was thinking about just happened. And no matter how many times I’ve tried to say there’s that thought/feeling again, I can’t let it go. I was physically conscious and could feel my body but mentally I couldn’t. It’s so weird and hard to explain. But I’ve been doubting and second guessing that moment all morning and I’m in a bad spiral, again. 😭 it’s like every time I think I’m moving forward I get sucked back in and feel like I can’t practice my tools anymore. I don’t know what I should do 😩
