Social and family conditioning is responsible for the guilt. Your emotions are just fine.

I don't really care one way or the other about my family. They were pretty religiously strict, kept me socially isolated by homeschooling until they stopped being able to and I went to real high school, made few if any attempts to engage with me as a person with independent agency when I started becoming an actual person in high school, and failed to navigate the transition between active parenting and becoming friends and trusted advisors with their adult children after they leave home. They weren't heavily abusive, just "mildly".

I'm now in my 30s and talk to them once in a while out of obligation. If they died I'd attend the funeral, enjoy a week of paid vacation bereavement leave with my girlfriend, and then probably never think about it again.

If you're upset with yourself, some counseling to learn to let go of toxic family relationships and accept yourself might help. If it's not that bad and you just need some reassurances... You're fine, really!
