I have no motivation now that I reconciled with my mother

For context, my mother abandoned me when I was 3 months old. She left me with a babysitter and never came back. I lived in foster care until I was 7 when she came to sign over her rights to me officially. She also only abandoned me she kept my brother and little sister. My whole life up untill the last few months I hated her. I blame every bad circumstance in childhood on her. When I eventually got adopted I made it my life goal to make her regret abandoning me, and to make realize she chose to abandon the wrong child. And due to that motivation I was able to get alot done. I graduated highschool at 17 and graduated with my bachelors degree at 19 and I currently work as a cybersecurity analyst. A few months ago she reached out to me and I was able to talk to her and realize that she a life way worse than me and that her giving me up was for the best. After this revelation, I feel like I have nothing.
