Accused of academic dishonesty

I’m meeting the dean of the school to explain my situation tomorrow. And I cited pretty much every evidence I gave in my research paper. I admit there was one or two sentences where it was word for word. But I cited it (I don’t think that really helps tbh). My defense I guess at this point was that it genuinely was unintentional. I used about 4-5 online plagarizing checker sites, talked with my professor on how to make this a better essay, and even went to my colleges writing center for help. I really did try my best and make this a good essay. I don’t know how it turned out like this. I hated this first year seminar but I still tried. My main concern is that everything is happening my freshman year. If this goes on my transcript, I’m basically screwed for law school so why try for the next three years. Why try at anything cause my future looks bleak. I don’t mind if they put it on the internal system cause I know I definitely will not do something like this again. I don’t even mind if they fail me and my gpa drops cause I know I can do better and raise it again. It’s just that stupid mark on the transcript.
