“What if I have no identity?”

Jesus Christ loves you Dalia. He’s waiting for you to call upon Him. In the Bible it says in Psalm 139:13-14 “For you formed my inward parts; you knitted me together in my mother's womb. I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well”. Go to Christ for he knew you before your were in the womb. He loves you.

I’ve had a very similar obsession before about the exact nature of my identity. It’s an area ocd likes to focus on because there’s a lot of uncertainty, there isn’t any way to “measure” how much of you is unique or yourself as opposed to influence from other people. That allows OCD to mess with those uncertainties and make you worry about the worst case scenario. Exposures can help you get more comfortable with the fears, often for things like this a written exposure will be used. For me it just took time and gradually getting more comfortable with the idea that I can’t know the exact nature of my identity, but it was very hard and stressful in the meantime. Keep going and you things will eventually get better.
