[UK] I got scammed in person how do I forgive myself and move on

I feel so ashamed and embarrassed that I fell for this, a pregnant woman approached me telling me that she fell and asking me for money and I stupidly complied and gave it to her. A minute after everything clicked and I felt so scared and stupid U approached her and asked for my money back to which she pushed me shouted at me and ran away. I asked people on the street to help me but nobody would which just further added to my shame she got her boyfriend to go after me and at that point I decided to give up because I didn’t want to get hurt. I feel so naive I can’t believe I fell for it red flags were going off when U was withdrawing the money and I just don’t know how to move forward. I feel this tight feeling in my chest however I can’t tell my parents because I just don’t know how I would approach this, I’ve got exams coming up and I’m so stressed and lacking focus. I have filed a police report but what should I do to not feel this feeling.
