Have you stopped to consider that maybe law isn't the problem, but the work environment of T-1 firms is what's bothering you? That maybe you don't actually find corporate law interesting enough?

I'd say give it some time, intern at boutique firms, try different areas of law (like IPR, ADR, Competition Law, Environmental Law etc. etc... yk the list is endless). Also, work at different roles- maybe you'd end up liking research or academia more than core practice? You'll never know until you try.

To make you feel a little better, I come from a non-NLU, above average private law school. Graduated this year. Had 4 offers and 2 confirmed assessment internships. Joined a boutique firm just a week after my final exams. Thought that was it, that I had my career sorted, I'd grow exponentially in the coming years. But life had other plans and I had to quit in barely 5 months. I realized practicing law wasn't a sustainable option for me. Thankfully, I had tried my hand at academic research and writing in law school and I know my love for research. So I decided not to concentrate on what I couldn't do anymore, but on what I can do and like doing. There's always a second chance, and thereafter a third chance, and a fourth one as well. You can choose to give yourself as many chances as you like before you finally stumble upon what you truly love doing. It's okay to not like what the majority is after.
