do folkshave any information in how OCD ruminations can become physical sensation?

Yes. If you are worried about reaching out and harming someone it can feel like your arm will really move, etc. It is called an ocd "urge" but not in the way people think of your average urge (as in NOT a deep desire or want)

Like i an looping that what if I felt certain feeling ? What does it say about me ? It’s making me feel so discouraged

Very common in ocd. You are obsessing and your compulsion seems to be emotional checking/rumination. The more you obsess about how you felt the more ocd digs you deeper. Ocd can cause false feelings or even if it wasn't your ocd it was just a random thing. The way you are responding shows that's not your values.

This is really helpful
