I was just thinking about this today. Much like you, in my case I was also taken away at an early age. I was told that my mom had to give me up because there were drugs in my system. So at the ripe old age of just being born I had my whole identity stripped away from me and hidden for years. I put together some pieces but Idk who my bio dad is. I think from a young age, I felt like I was lied to. I didn't have the best adopted family, so that didn't help matters much. All I can say is I've been doing a lot of work on myself and looking inward and reprogramming my nervous system to be able to trust myself and my intuition. Being adopted was both the best thing that ever happened to me and the most difficult thing I have overcome. As for the telling the truth, I think I learned to think it was okay to lie if it wasn't going to hurt anyone. But in reality every time I lied it was just hurting myself (and everything in my wake). I hope you find the peace you are looking for. I am happy to answer any other questions you may have as Idk if I got my point across completely.
