Can someone explain what OCD and the "ick" is?

The ick can be normal in any relationship.... However if u have rocd it can turn into an obsession. Constantly thinking negatively, doing compulsions that feed into the cycle that only make u feel worse. The anxiety, stress and emotional distress that can be caused by rocd is the worst.

It's an old "Sex In The City" reference to Leanne (you know, the "uptight one" 🙄) but it resonated with millions. Not only is the Ick the gross slime disease aquarium fish can get on their feet, Leanne was describing that point in a relationship when everything your partner does grosses you out. Here's a silly Women's Health article I saw about it - https://www.womenshealthmag.com/relationships/a37550106/what-is-the-ick/

Is that like a normal faze in the relationship?

Depends. I agree with the article where I think it's normal if two people OD on new relationship energy and spend 24/7 together and need breathing room for a bit, and not "normal" (what is this "normal"?) when it's toxic. I've done both of these things on both ends. Sometimes, me and another were better friends than anything more, other times, I have been an uptight ass and put my negapuss energy on my lover. I also probably have the cute matching personality disorder too. I'm better than ever and striving daily. Meds with the right doctor who listened to my symptoms and believed me have been life-changing.
