I was step parent adopted at a very young age and only discovered my step father wasn't my biological Dad when I was 16. Mum wouldn't tell me anything about my bio Dad other than a name which turned out to be false. Obtaining my adoption records years later revealed very little. The social worker clearly wasn't very diligent as the entire adoption report was less than half a sheet of A4. I spent years painstakingly searching and finally took a DNA test hoping this would give me the answers I needed. My bio Dad was dead but I did meet a half sibling. I wish I hadn't. My bio Dad spent most of his life in and out of prison, and committed some really heinous crimes. He never had a job. I feel absolutely despairing, ashamed, and embarrassed knowing I carry the DNA of such an awful individual and am struggling to cope. I literally have none to discuss this with because it's so sickening. My very supportive husband spent months painstakingly researching through matches on Ancestry because he knew how I felt not knowing half my identity. I don't want to appear ungrateful by telling him how utterly depressed I feel. The contact I had with my half sibling ended fairly quickly as we had little in common. I don't have any children which is something of a relief that the bad genes end with me. How do I move forward from this? I've considered counselling but I worry that no one would understand or see me as deserving.
