Feeling sad and disappointed

Hi, I’m going to try not to make this too long but I’m just feeling really upset and I need to rant. This is my first year of college currently first semester and everything. It has been extremely challenging adjusting to it all. I’m failing 1 class right now and I have no idea how to fix that. I have tried studying for our quizzes but I guess it’s just not enough. But what my mind is on what happened to me today. The english class I am in is your average GE class but for me it’s so challenging. Today we had a three paged paper due. Because I was away this weekend I started it late last night while I did the first page all myself then I fell asleep while writing the rest. I woke up this morning late and was frantically trying to finish before I had to go to my first class. Anyways I found this essay from some random online website and long story short I kinda copied most of it to my paper and just changed a few things so that I could just turn in my rough draft then actually have time to do the rest myself for the final draft. Hoping my teacher wouldn’t even notice, I submitted it. In the middle of class today he angrily asks to see my outside meanwhile the class was dead quiet with the door open so I knew they could all hear. He went on to tell me he knew I plagiarized 80% of it and since “I’m a first time first semester freshman who doesn’t know anything” he won’t report me to judicial affairs to get me expelled. He went on and on about it all and told me I am getting a zero for the whole assignment. He ended with saying “just get your stuff and go home.” At first I was embarrassed obviously, then I was just so angry. I was angry at myself for trying to fit it all in this morning. But it’s college has really sucked for me now I’m going to be failing two classes. Everyday is a challenge. Every single day. I have never been so disappointed in myself in my life. I cried in the middle of the class and I feel like such a horrible person. It’s not like I was lazy and copied someone’s work because I wanted to. I just wanted to turn in something at all because I didn’t want to just slack off and not turn it in because I didn’t finish. I was so concerned with turning it in I guess I didn’t care? The fact that he said “you’re getting a zero on this so you can just get your stuff and go home” has been replaying in my head all day. I’m scared to go to class I’m scared to even try at all. I don’t know what to do.
