How do I stop thinking about women? I try some hobbies and do some productive things but it still won't budge, overtime it worsens my body dysmorphia and makes me feel ashamed for being who I am right now (normal dude who isn't buff)

I need to move on from this phase as fast as I can so I that whenever I'm trying to get better, it is for God and not her.

Immerse yourself in a productive hobby
