ex best friend in same career as me

I don’t know if I am being dramatic about this, but it is messing with me. About two years ago, I (22F) had a huge falling out with a friend (22F). We both made mistakes, but I was mainly hurt because she betrayed me after I had been there for her repeatedly during her abusive relationship. She made me feel like the worst person ever after I confronted her about it. I was questioning my self worth and lived in shame for months after she cut me off that I even ended up going to therapy over it. I also ended up losing another friend over this situation because she took sides. She later sent me a long apology text, to which I accepted and also apologized for my part. But, I ended up just cutting her off in the end because the way she made me feel is something I will never forget.

I am currently applying to law school and have been interested in law since my freshman year of college. I have always loved law and school/education was always a comfort to me. I had gone back and forth about committing to law school because of the loans, time commitment, and difficulty. But ultimately decide to bite the bullet and just try to take the LSAT and apply. Well, my ex friend keeps showing up on my social medias where she is sharing her journey of getting into law school.

I know it may be unfair of me to gatekeep a literal entire career, but I don’t know why her being in the same career field as me is making me sick to my stomach. The one thing I was proud of and felt like was mine is also being taken up by someone who seriously hurt me mentally. I almost thought about switching careers just over this which I know sounds crazy but it’s just how I feel. We also live in the same area so I would hate to have to interact with her while we are both in our careers.

tldr: ex friend who really hurt me is going to law school just like me. It’s really messing with me and I don’t know why
