Struggling

So to start things off I have an issue with comparing myself. I often have the compulsion to go on Pinterest and look up certain female celebrities and compare myself or just sigh and feel bad because I don’t look like them etc. Unfortunately my ocd has attached to it :( I’ve had thoughts like “No you keep looking for other reasons” or even “This means you’re a bad fiancé” and it makes me freak and spiral, and then my ocd will attack me and make me feel like I’m being disrespectful or unloyal to my relationship. It’s so bothersome, it’s like my ocd has attached to these certain female celebrities and it’s like my compulsion is like I have this urge to click on the photo and if I don’t I worry about if something will happen etc. What’s weird is that sometimes when I’m just doom scrolling through some of these celebrities pictures and feeling upset I feel embarrassed because I’m pretty sure I’m embarrassed of the compulsion itself because it’s a weird compulsion to have and it’s just really bothering me so much. I really hate this and I’ve told my fiancé about it and he always helps me but i dont know how to just sit with this it’s too bothersome and feels awful :( has anyone else dealt with this?
